Learn to Code SQL Example – SQL Server Mathematical functions (SQRT, PI, SQUARE, ROUND, CEILING & FLOOR)

(SQL Example for Citizen Data Scientist & Business Analyst)


SQL Server Mathematical functions (SQRT, PI, SQUARE, ROUND, CEILING & FLOOR)

Mathematical functions are present in SQL server which can be used to perform mathematical calculations. Some commonly used mathematical functions are given below:
1. SQRT():
SQRT() function is the most commonly used function. It takes any numeric values and returns the square root value of that number.


SELECT SQRT(..value..)


2. PI(): There are calculations which require use of pi. Using pi() function, value of PI can be used anywhere in the query.




3. SQUARE(): SQUARE() function is used to find the square of any number.


SELECT SQUARE(..value..)


4. ROUND(): ROUND() function is used to round a value to the nearest specified decimal place.


SELECT ROUND(..value.., number_of_decimal_places)


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).

SELECT FLOOR(..value..)
