This page covers all the MySQL Math functions with their descriptions for reference.
| Name | Description |
|---|---|
| ABS() | Returns the absolute value of a number |
| CEIL() | Returns the smallest integer value greater than or equal to the input number (n). |
| FLOOR() | Returns the largest integer value not greater than the argument |
| MOD() | Returns the remainder of a number divided by another |
| ROUND() | Rounds a number to a specified number of decimal places. |

| ATAN2(n,m), ATAN(m,n) | Returns the arctangent of the two variables n and m |
| CONV(n,from_base,to_base) | Converts a number between different number bases |
| COS(n) | Returns the cosine of n, where n is in radians |
| COT(n) | Returns the cotangent of n. |
| CRC32() | Computes a cyclic redundancy check value and returns a 32-bit unsigned value |
| DEGREES(n) | Converts radians to degrees of the argument n |
| EXP(n) | Raises to the power of e raised to the power of n |

| LOG(n) | Returns the natural logarithm of the first argument |
| LOG10() | Returns the base-10 logarithm of the argument |
| LOG2() | Returns the base-2 logarithm of the argument |
| PI() | Returns the value of PI |
| POW() | Returns the argument raised to the specified power |
| POWER() | Returns the argument raised to the specified power |
| RADIANS() | Returns argument converted to radians |
| RAND() | Returns a random floating-point value |
| SIGN(n) | Returns the sign of n that can be -1, 0, or 1 depending on whether n is negative, zero, or positive. |
