Java(25)-Math Class Methods

class apples{

public static void main(String args[]){

System.out.println(Math.abs(-26.7));

System.out.println(Math.ceil(7.4));

System.out.println(Math.floor(7.8));

System.out.println(Math.max(8.6,5.2));

System.out.println(Math.min(8.6,5.2));

System.out.println(Math.pow(5,3));

System.out.println(Math.sqrt(9));

}

}

(Math.abs(-26.7)); →ABS意味著絶對值

(Math.ceil(7.4)); →值將四捨五入= 8

(Math.floor(7.8)); →值將向下舍入= 7

(Math.max(8.6,5.2)); →比較，數量是最大

(Math.min(8.6,5.2)); →比較數量最低

(Math.pow(5,3)); → 5*5*5 = 125

(Math.sqrt(9)); → 9 =3的平方根

該Program將運行這樣的：

26.7

8.0

7.0

8.6

5.2

125.0

3.0
