This class provides the standard mathematical functions, using types int, long, float and double as appropriate.
It is a static class, meaning that you only use the methods, never creating objects from this class.
The methods include
IEEEremainder, abs, ceil, cos, exp, floor, log, max, min, pow, random, sin, sqrt, and other trig functions.
The random number generator is a linear congruential generator, which is fast but not random enough for many scientific applications.
