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
