Java中将一个BigDecimal乘以另一个BigDecimal
使用该multiply()方法在Java中将一个BigDecimal乘以另一个。此方法返回一个BigDecimal，其值为（this×被乘数），其标度为（this.scale()+multiplicand.scale()）。
以下是一个例子-
示例
import java.math.BigDecimal;
public class Demo {
public static void main(String[] argv) throws Exception {
BigDecimal val1 = new BigDecimal("375789755.345778656");
BigDecimal val2 = new BigDecimal("525678755.155778656");
System.out.println("Value 1 = "+val1);
System.out.println("Value 2 = "+val2);
val2 = val2.multiply(val1);
System.out.println("Result (Multiplication) = "+val2);
}
}输出结果
Value 1 = 375789755.345778656 Value 2 = 525678755.155778656 Result (Multiplication) = 197544690790463541.417987494305166336
让我们看另一个例子-
示例
import java.math.*;
public class Demo {
public static void main(String[] args) {
BigDecimal bg1, bg2, bg3;
bg1 = new BigDecimal("58.98");
bg2 = new BigDecimal("78.89");
bg3 = bg1.multiply(bg2);
String str = "Multiplication = " +bg3;
System.out.println( str );
}
}输出结果
Multiplication = 4652.9322
