Java.math.BigDecimal.divide() Method



The java.math.BigDecimal.divide(BigDecimal divisor, int roundingMode) returns a BigDecimal whose value is (this / divisor), and whose scale is this.scale(). If rounding must be performed to generate a result with the given scale, the specified rounding mode is applied.


Following is the declaration for java.math.BigDecimal.divide() method

public BigDecimal divide(BigDecimal divisor, int roundingMode)


  • divisor - value by which this BigDecimal is to be divided

  • roundingMode - rounding mode to apply

Return Value

This method returns a BigDecimal object whose value is this / divisor, rounded as specified


  • ArithmeticException - if divisor == 0, or roundingMode == ROUND_UNNECESSARY and this.scale() is insufficient to represent the result of the division exactly

  • IllegalArgumentException - if roundingMode does not represent a valid rounding mode


The following example shows the usage of math.BigDecimal.divide() method.

package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

public static void main(String[] args) {

        // create 3 BigDecimal objects
        BigDecimal bg1, bg2, bg3;

        bg1 = new BigDecimal("16");
        bg2 = new BigDecimal("3");

        // divide bg1 with bg2
	// 0 specifies BigDecimal.ROUND_UP
	bg3 = bg1.divide(bg2, 0);

        String str = "Division result is " +bg3;

	// print bg3 value
	System.out.println( str );

Let us compile and run the above program, this will produce the following result:

Division result is 6
