Java API of Math package
1 In Java, additional mathematical operators are given in a package called Math as methods. These methods typically use arguments and results of type double. To compute exponents:
2 The API: public static double pow(double a, double b)
3 To use it:
4 Also: public static double sqrt (double a )
5 And many more, such as sin, cos, min, max!
6 double x, y, z ;
7 x = 1.5 ;
