PHP has several built-in functions for performing mathematical operations.

A list of PHP math operation functions can be found in the table below:

Math Functions

abs(): Returns the absolute value of the argument.
acos(): Returns the angle whose cosine value is equal to the specified value.
acosh(): Returns the inverse hyperbolic cosine value of the given argument.
asin(): Returns the arc sine of a given number.
asinh(): Returns the inverse hyperbolic sine of a number.
atan(): Returns the angle whose tangent is equal to the specified value.
atan2(): Returns the arc tangent of y/x, in radians.
atanh(): Returns the inverse hyperbolic tangent of a given value.
base_convert(): Converts a number from one number base to another.
