算術函數運算

public class MFUN {public static void main(String[]args){float a=3,b=4;System.out.println("exp(a)="+Math.exp(a));System.out.println("log(a)="+Math.log(a));System.out.println("sqr(a)="+Math.sqrt(a));System.out.println("abs(-a*b)="+Math.abs(-a*b));System.out.println("3*3*3*3="+Math.pow(a,b));System.out.println("max(a,b)="+Math.max(a,b));//取a,b的較大者}}

結果：

exp(a)=20.085536923187668log(a)=1.0986122886681098sqr(a)=1.7320508075688772abs(-a*b)=12.03*3*3*3=81.0max(a,b)=4.0
