    代码

    package com.nash.java.pop.ch06_math;
    
    public class MathApp {
    
        /**
         * Math 静态类方法
         * @param args
         */
        public static void main(String[] args) {
    
            System.out.println("Math.max(2,10):\t " + Math.max(2,10));
            System.out.println("Math.max(2.6,7.5):\t " + Math.max(2.6,7.5));
            System.out.println("Math.abs(-100):\t " + Math.abs(-100));
            System.out.println("Math.abs(-100.30):\t " + Math.abs(-100.30));
            System.out.println("Math.acos(1):\t " + Math.acos(1));
            System.out.println("Math.ceil(2.6):\t " + Math.ceil(2.6));
            System.out.println("Math.floor(2.6):\t " + Math.floor(2.6));
            System.out.println("Math.exp(Math.E):\t " + Math.exp(Math.E));
            System.out.println("Math.min(2,10):\t " + Math.min(2,10));
            System.out.println("Math.round(2.6):\t " + Math.round(2.6));
            System.out.println("Math.random():\t " + Math.random());
        }
    }
    
    

    结果

    Math.max(2,10):  10
    Math.max(2.6,7.5):   7.5
    Math.abs(-100):  100
    Math.abs(-100.30):   100.3
    Math.acos(1):    0.0
    Math.ceil(2.6):  3.0
    Math.floor(2.6):     2.0
    Math.exp(Math.E):    15.154262241479262
    Math.min(2,10):  2
    Math.round(2.6):     3
    Math.random():   0.05924174741095978
