import java.math.BigDecimal;
public class DecimalTest {
public static void main(String[] args) {
System.out.println("7.22-7.0="+subtractTest(7.2882,7.10));
}
private static double subtractTest(double v, double v1) {
BigDecimal b1 = new BigDecimal(Double.toString(v));
BigDecimal b2 = new BigDecimal(Double.toString(v1));
System.out.println("b1=>"+b1+" b2=>"+b2);
return b1.subtract(b2).doubleValue();
}
}
输出打印为:
b1=>7.2882 b2=>7.1
7.22-7.0=0.1882
