public BigDecimal abs(MathContext mc)

Parameters

mc − The context to use.

Return Value

This method returns the absolute value of the called value i.e abs(this), rounded as necessary.

Example

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

package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

   public static void main(String[] args) {

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

      MathContext mc = new MathContext(2);
      MathContext mc1 = new MathContext(4);

      // assign value to bg1
      bg1 = new BigDecimal("40.1234");

      // assign absolute value of bg1 to bg2 rounded to 2 precision using mc
      bg2 = bg1.abs(mc);

      // assign absolute value of bg1 to bg3 rounded to 4 precision using mc1
      bg3 = bg1.abs(mc1);

      String str1,str2;
      str1 = "Absolute value, rounded to 2 precision is " + bg2;
      str2 = "Absolute value, rounded to 4 precision is " + bg3;

      // print bg2 and bg3 value
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

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

Absolute value, rounded to 2 precision is 40
Absolute value, rounded to 4 precision is 40.12
