Multiply one BigDecimal to another BigDecimal in Java

Use the multiply() method to multiply one BigDecimal to another in Java. This method returns a BigDecimal whose value is (this × multiplicand), and whose scale is (this.scale() + multiplicand.scale()).

The following is an example −

Example

Live Demo

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);
}
}

Output

Value 1 = 375789755.345778656
Value 2 = 525678755.155778656
Result (Multiplication) = 197544690790463541.417987494305166336

Let us see another example −

Example

Live Demo

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 );
}
}

Output

Multiplication = 4652.9322
