The Math class provides a set of static methods for performing common arithmetic, exponential and trigonometric functions.

It also provides commonly used constants such as PI. See also the Number class. Depending on the method and the supplied argument, return values may be real numbers, NaN (not a number) or positive or negative infinity.
