例子
下面的例子显示math.BigDecimal.signum()方法的用法package com.yiibai;import java.math.*;public class BigDecimalDemo {
public static void main(String[] args) {
// create 3 BigDecimal objects
BigDecimal bg1, bg2, bg3;
// create 3 int objects
int i1, i2, i3;
bg1 = new BigDecimal("123");
bg2 = new BigDecimal("0");
bg3 = new BigDecimal("-12");
// assign the signum values of bg1,bg2,bg3 to i1,i2,i3 respectively
i1 = bg1.signum();
i2 = bg2.signum();
i3 = bg3.signum();
String str1 = "The Result of Signum function on " + bg1 + " is " + i1;
String str2 = "The Result of Signum function on " + bg2 + " is " + i2;
String str3 = "The Result of Signum function on " + bg3 + " is " + i3;
// print i1,i2,i3 values
System.out.println( str1 );
System.out.println( str2 );
System.out.println( str3 );
}}
让我们来编译和运行上面的程序,这将产生以下结果:The Result of Signum function on 123 is 1
The Result of Signum function on 0 is 0
The Result of Signum function on -12 is -1
