java例程练习（Math类）

public class Test { public static void main(String[] args) { double a = Math.random(); double b = Math.random(); System.out.println(Math.sqrt(a*a+b*b)); System.out.println(Math.pow(a, 8)); System.out.println(Math.round(b)); System.out.println(Math.log(Math.pow(Math.E, 15))); double d = 60.0; double r = Math.PI / 4; System.out.println(Math.toRadians(d)); System.out.println(Math.toDegrees(r)); System.out.println(Math.PI); System.out.println(Math.E); } }
