Quick Guide to MySQL Math Functions for SQL Users

MySQL math functions simplify calculations within SQL queries, valuable for developers and analysts alike. Whether you’re rounding numbers, calculating angles, or determining remainders, these functions provide straightforward solutions for common database tasks.

MySQL Math Functions

Here are some useful MySQL math functions and their practical applications:

ABS(): Returns the absolute value, often used to handle values regardless of sign in financial and analytic operations.

SELECT ABS(-10); -- returns 10

COS() and ACOS(): Essential for trigonometric calculations, used in fields requiring geometric or distance computations.

SELECT COS(0); -- returns 1

DEGREES(): Converts radians into degrees, ideal for spatial and mapping-related calculations.

SELECT DEGREES(PI()); -- returns 180

FLOOR(): Rounds down to the nearest integer, often applied in pricing or unit-based calculations.

SELECT FLOOR(3.14); -- returns 3

MOD(): Calculates the remainder, useful for batch processing or ensuring divisibility in sequences.

SELECT MOD(9, 2); -- returns 1

These functions make it easier to perform complex mathematical operations directly within SQL, saving time and enhancing query accuracy.
