In this video, overview of Oracle predefined Number functions is given.
SQL Used in the video given below.
ABS - Absolute function returns absolute value. i.e it returns positive value.
select abs(-18.9), abs(8.9), abs(0) from dual;
FLOOR and CEIL
For 10.2, floor returns value 10, ceil returns value 11
select floor(10.8), ceil(10.2) from dual;
ROUND
select round(10.8), round(10.49) from dual;
SELECT round(10.483,1) from dual;
select round(3548,-1),round(3548,-2),round(3548,-3) from dual;
select round(3568,-1),round(3568,-2),round(3268,-3) from dual;
MOD - returns me the remainder..
let's say 11 divided by 3, here the remainder is 2
select mod(12,3) from dual;
select sign (-10), sign (0), sign(10) from dual;

The Oracle TO_NUMBER function is used to convert a text value into a number value.
It’s similar to TO_CHAR and TO_DATE, but converts a value to a number.
The number will also be rounded to a specified number of digits, and returned as a NUMBER value.
The syntax is:
TO_NUMBER( input_value, [format_mask], [nls_parameter] )
The input_value is the value to be converted to a number. Commonly this is provided as a string (e.g. CHAR or VARCAHR2) but can be several other data types as well.
The format_mask is the format that the output value should be displayed as. It must be a valid number format. This is an optional value.
The final parameter, nls_date_language, is used to work out how the output is displayed, such as how to display currency symbols. It’s also an optional value.
For more information about the Oracle TO_NUMBER function, including all of the SQL shown in this video and the examples, read the related article here:

https://www.databasestar.com/oracle-remainder-mod/
The Oracle MOD function performs a “modulo division” on the numbers you specify. A modulo division is where a division is performed using two numbers, and the remainder is returned by the function.
For example, the division of 8/5 is 1.6. Using modulo division, 8/5 will work out there is one 5 contained in the 8, with 3 left over. The MOD function would return 3 in this example.
The syntax of the MOD function is:
MOD(numerator, denominator)
The numerator is the number mentioned first in the division, or the one that is on top of the division sign. In a division such as 15/4, this would be the 15.
The denominator is the number mentioned second in the devision, or hte one that is on the bottom of the division sign. In a division such as 15/4, this would be the 4.
The parameters can be any numeric data type, and the return type depends on these parameters. This means MOD can return a whole number or a decimal number.
The calculation for the Oracle MOD function is: numerator - denominator * FLOOR(numerator / denominator).
If the denominator is 0, the function returns the value of the numerator. This is done to prevent “divide by 0” errors.
For more information about the MOD function, including how to return every second row, how it’s different to REMAINDER, and to see the SQL code used in these examples, read the related article here:

https://www.databasestar.com/oracle-greatest/
The Oracle GREATEST function is a useful function, but I don’t think it’s very well understood.
It returns the greatest or largest value in a set of values. You can provide the values, and use numbers or text values.
The syntax for the Oracle GREATEST function is:
GREATEST(expr1 [, expr_n])
The expr1 is the first expression to use for your comparison. Expr_n is one or more expressions to use in the comparison, separated by commas. This is optional.
So how is GREATEST calculated?
If the parameters are numeric, the GREATEST function finds the largest number.
If the parameters are characters, the function finds the latest value if they were sorted alphabetically (using their character values).
What data type is returned?
It depends on the parameters you provide. It could be the same as the parameters you provide, or VARCHAR2 if the parameters are all characters.
You can also use the GREATEST function with dates.
It’s also the opposite of the LEAST function.
For more information on the GREATEST function, including the SQL used in this video and the examples, read the related post here:

https://www.databasestar.com/oracle-lpad/
The Oracle LPAD function is used to add extra characters to the left of a text value. This is called “padding”, and the function is called LPAD because the L stands for “left” and it “left pads” a text value.
It’s the opposite of RPAD, which pads characters to the right of the value.
The LPAD function can be useful for ensuring all values are the same length, or if there is another requirement you have for adding characters to the end.
The syntax is:
LPAD(expr, length [,pad_expression])
The expr parameter is the text value you want to pad or add characters to.
The length is the total length the expression or value will be after the padding has been done. It’s not the number of characters to add.
The pad_expression is an optional field and is the character or characters to add to the left end of the string. The default value is a space.
If the length specified in the function is shorter than the length of the string, then the string is truncated to meet the length.

https://www.databasestar.com/oracle-add_months/
The Oracle ADD_MONTHS allows you to add a specified number of months to a date value, and return the new date value. It’s great for performing calculations on dates, or date arithmetic, which can be hard in many different programming languages.
The syntax of the ADD_MONTHS function is:
ADD_MONTHS ( input_date, number_months )
The function returns a DATE value.
The parameters of this function are:
- input_date (mandatory): This is the starting date, or the date that you will add a number of months to.
- number_months (mandatory): This is an integer value that represents the number of months to add to input_date.
The input_date can be any datetime value, or even a character value that can be converted to a date. Also, the number_months can be any number value, or a character value that can be converted to a number.
What if the number of days in the two months are different? For example, adding a month to Jan 31 could result in Feb 31, which does not exist. Well, in this case, Oracle would work out that the date does not exist, and use the last date of the month (e.g. Feb 28).
You can also provide a negative value for ADD_MONTHS to subtract months from the specified date.

https://www.databasestar.com/oracle-months_between/
The Oracle MONTHS_BETWEEN function allows you to find the number of months between two dates. You can enter two dates and the function returns the difference.
This function is often used as part of other calculations. Sometimes you’ll want to know the difference between two dates to perform other functions.
The syntax of the MONTHS_BETWEEN function is:
MONTHS_BETWEEN(date1, date2)
What do these two parameters mean?
The function performs date1 minus date2. So, if date1 is larger, the result is positive. If date2 is larger, then the result is negative.
What data type is returned?
It depends on the values you provide. If the dates are both on the same day of the month (e.g. both on the 10th of the month), then the result is an integer or whole number. If not, then the result will be a decimal value.

The Oracle EXP function returns the mathematical value of e raised to the nth power. EXP is short for “exponential”.
The value of “e” is a mathematical constant, and it’s roughly equal to 2.71.
The syntax of the EXP function is:
EXP( number )
We don't need to specify the value of e, because it's a standard value (kind of like pi).
The parameter for EXP is a number which represents the power to raise e to. For example, if the number is 2, then the function calculates e to the power of 2 and returns that number.

The Oracle FLOOR function will return the largest integer value less than the specified number. In other words, it rounds down to the nearest whole number.
It’s the opposite of the CEIL function, which rounds up.
The syntax of FLOOR is:
FLOOR(number)
The number parameter can be any numeric data type. The function will return a number in the same data type as the parameter.
So, you can use FLOOR with decimal numbers, which is actually where FLOOR works best. You can use it with whole numbers too. It won’t show an error, it just might display the same value as provided (e.g. FLOOR(5) would be 5).
You can also use functions inside FLOOR. For example, FLOOR(SUM(salary)) will SUM all of the salary values, and then round them down to the nearest whole number.
Just like with all functions, the Oracle FLOOR function can also use column aliases. So, instead of having your column labelled “FLOOR(8.12)” or “FLOOR(salary)”, you can label your column “salary_rounded” or something that makes more sense.
The FLOOR function is similar to the ROUND function. However, ROUND will round up or down, where FLOOR will always round down. The TRUNC function will also do some kind of rounding, but it removes decimals from a number which may cause it to “round” down.

https://www.databasestar.com/oracle-trim/
The Oracle RTRIM function allows you to remove a specific character from the right side of a string.
It’s one of the most commonly used string manipulation functions in SQL, in my experience. The “R” in “RTRIM” stands for “right”.
It’s often used to remove spaces from the right of a string. However it can be used to remove other characters, such as trailing slashes from URLs.
The syntax for the RTRIM function is:
RTRIM(input_string, [trim_character])
The input_string is the text you want to remove characters from. It can be any kind of expression, such as a specific text value or a column.
The trim_character is the character you want to remove from the right of the string. It’s an optional parameter, and if you don’t specify it, then a space character is used by the function.
The parameters can be any type of string. The function will return either a VARCHAR2 or a LOB data type, depending on the type of data you specify in the parameters.
You can specify more than one value for the trim_character, and the RTRIM function will remove both characters from the right of the string.
The function is similar to the LTRIM value, where LTRIM removes characters from the left of the string.

The Oracle CEIL function, short for “ceiling”, will return the smallest integer value greater than the specified number. In other words, it rounds up to the nearest whole number.
It’s the opposite of the FLOOR function, which rounds down.
The syntax of CEIL is:
CEIL(number)
The number parameter can be any numeric data type. The CEIL function will return a number in the same data type as the parameter.
So, you can use CEIL with decimal numbers, which is actually where CEIL works best. You can use it with whole numbers too. It won’t show an error, it just might display the same value as provided (e.g. CEIL(8) would be 8).
You can also use functions inside CEIL. For example, CEIL(SUM(salary)) will SUM all of the salary values, and then round them up to the nearest whole number.
Like with all functions, the Oracle CEIL function can also use column aliases. So, instead of having your column labelled “CEIL(8.12)” or “CEIL(salary)”, you can label your column “salary_rounded” or something that makes more sense.
The CEIL function is similar to the ROUND function. However, ROUND will round up or down, where CEIL will always round up. The TRUNC function will also do some kind of rounding, but it removes decimals from a number which may cause it to “round” down.

This video will provide you the details of each Mathematical Function in SQL Server 2014.
***********************************************************************
ABS (Transact-SQL)
A mathematical function that returns the absolute (positive) value of the specified numeric expression.
Syntax
ABS ( numeric_expression )
Arguments
numeric_expression
Is an expression of the exact numeric or approximate numeric data type category.
Return Types
Returns the same type as numeric_expression.
Examples
The following example shows the results of using the ABS function on three different numbers.
SELECT ABS(-1.0), ABS(0.0), ABS(1.0);
Here is the result set.
---- ---- ----
1.0 .0 1.0
The ABS function can produce an overflow error when the absolute value of a number is greater than the largest number that can be represented by the specified data type. For example, the int data type can hold only values that range from -2,147,483,648 to 2,147,483,647. Computing the absolute value for the signed integer -2,147,483,648 causes an overflow error because its absolute value is greater than the positive range for the int data type.
DECLARE @i int;
SET @i = -2147483648;
SELECT ABS(@i);
***********************************************************************
CEILING (Transact-SQL)
Returns the smallest integer greater than, or equal to, the specified numeric expression.
Syntax
CEILING ( numeric_expression )
Arguments
numeric_expression
Is an expression of the exact numeric or approximate numeric data type category, except for the bit data type.
Return Types
Returns the same type as numeric_expression.
Examples
The following example shows positive numeric, negative, and zero values with the CEILING function.
SELECT CEILING($123.45), CEILING($-123.45), CEILING($0.0);
GO
***********************************************************************
FLOOR (Transact-SQL)
Returns the largest integer less than or equal to the specified numeric expression.
Syntax
FLOOR ( numeric_expression )
Arguments
numeric_expression
Is an expression of the exact numeric or approximate numeric data type category, except for the bit data type.
Return Types
Returns the same type as numeric_expression.
Examples
The following example shows positive numeric, negative numeric, and currency values with the FLOOR function.
SELECT FLOOR(123.45), FLOOR(-123.45), FLOOR($123.45);
***********************************************************************
POWER (Transact-SQL)
Returns the value of the specified expression to the specified power.
Syntax
POWER ( float_expression , y )
Arguments
float_expression
Is an expression of type float or of a type that can be implicitly converted to float.
y
Is the power to which to raise float_expression. y can be an expression of the exact numeric or approximate numeric data type category, except for thebit data type.
Return Types
Returns the same type as submitted in float_expression. For example, if a decimal(2,0) is submitted as float_expression, the result returned isdecimal(2,0).
Examples
A. Using POWER to return the cube of a number
The following example demonstrates raising a number to the power of 3 (the cube of the number).
DECLARE @input1 float;
DECLARE @input2 float;
SET @input1= 2;
SET @input2 = 2.5;
SELECT POWER(@input1, 3) AS Result1, POWER(@input2, 3) AS Result2;

This video is the 5th video in the series of 'working with null', this video explains the working of the lnnvl function in oracle sql with simple and easy to understand example.
LNNVL provides a concise way to evaluate a condition when one or both operands of the condition may be null. The function can be used only in the WHERE clause of a query.
It takes as an argument a condition and returns TRUE if the condition is FALSE or UNKNOWN and FALSE if the condition is TRUE.
LNNVL can be used anywhere a scalar expression can appear, even in contexts where the IS [NOT] NULL, AND, or OR conditions are not valid but would otherwise be required to account for potential nulls. Oracle Database sometimes uses the LNNVL function internally in this way to rewrite NOT IN conditions as NOT EXISTS conditions.
In such cases, output from EXPLAIN PLAN shows this operation in the plan table output. The condition can evaluate any scalar values but cannot be a compound condition containing AND, OR, or BETWEEN.
