mysql includes a bunch of functions and operators that can help us when working with data.

The following is a list of mathematical functions available in MySQL. You can click on each function name to see an explanation of the function, its syntax, and examples.

ABS() Returns the absolute value of a given value. ACOS() Returns the arc cosine of a number. ASIN() Returns the arc sine of a number. ATAN() Returns the arc tangent of a value (or values). ATAN2() Returns the arc tangent of the two arguments. CEIL() Synonym for CEILING() . CEILING() Rounds a number up to the nearest integer (returns the smallest integer not less than its argument). CONV() Convert numbers between different number bases. COS() Returns the cosine of a number. COT() Returns the cotangent of a number. CRC32() Computes a cyclic redundancy check value. DEGREES() Converts from radians to degrees. EXP() Returns e to the power of x . FLOOR() Rounds a number down to the nearest integer (returns the largest integer value not greater than the argument). LN() Returns the natural logarithm of a number. LOG() Returns the natural logarithm of a number. Also allows you to specify the base. LOG10() Returns the base-10 logarithm of the argument. LOG2() Returns the base-2 logarithm of the argument. MOD() Performs a modulo operation. Returns the remainder of N divided by M . PI() Returns the value of π (pi). POW() Return the argument raised to the specified power. POWER() Synonym for POW() . RADIANS() Converts a value from degrees to radians, and returns the result. RAND() Returns a random floating-point value. ROUND() Rounds a number up or down to a given number of decimal places. SIGN() Returns the sign of the argument (so you can know whether a number is positive or negative). SIN() Returns the sine of the argument. SQRT() Returns the square root of the argument. TAN() Returns the tangent of the argument. TRUNCATE() Truncates a value to specified number of decimal places.
