 Chapter 25The java.lang Package

## 25.37 java.lang.Math (JDK 1.0)

This class defines constants for the mathematical values e and pi, and defines static methods for floating-point trigonometry, exponentiation, and other operations. It is the equivalent of the C <math.h> functions. It also contains methods for computing minimum and maximum values and for generating pseudo-random numbers.

```public final class Math extends Object {
// No Constructor
// Constants
public static final double E;
public static final double PI;
// Class Methods
public static native double IEEEremainder(double f1, double f2);
