Mathematical functions are present in SQL server which can be used to perform mathematical calculations. Some commonly used mathematical functions are given below:
SQRT() function is the most commonly used function. It takes any numeric values and returns the square root value of that number.
2. PI(): There are calculations which require use of pi. Using pi() function, value of PI can be used anywhere in the query.

5. CEILING() and FLOOR()
CEILING(): CEILING() function is used to find the next highest value (integer).
FLOOR(): FLOOR() function returns the next lowest value (integer).
