BigDecimal stripTrailingZeros() Method in Java

  • Last Updated : 04 Dec, 2018

The java.math.BigDecimal.stripTrailingZeros() is an inbuilt method in Java that returns a BigDecimal which is numerically equal to this one but with any trailing zeros removed from the representation. So basically the function trims off the trailing zero from the BigDecimal value.

Syntax:

public BigDecimal stripTrailingZeros()

Parameter: This method does not accepts any parameter.

Return value: This method returns a numerical value equal to the BigDecimal with all the trailing zeros being removed.

Examples:



Input: 785.000
Output: 785

Input: 125500000
Output: 1.255E+8

Below programs illustrate the working of the above mentioned method:
Program 1:




// Program to demonstrate stripTrailingZeros() method of BigDecimal 
  
import java.math.*;
  
public class Gfg {
  
    public static void main(String[] args)
    {
  
        BigDecimal b1 = new BigDecimal("785.000");
        BigDecimal b2 = new BigDecimal("125500");
  
        // Assigning the result of stripTrailingZeros method
        // to BigDecimal objects b3, b4
        BigDecimal b3 = b1.stripTrailingZeros();
        BigDecimal b4 = b2.stripTrailingZeros();
  
        // print b3, b4 values
        System.out.println(b1 + " after removing trailing zeros " + b3);
        System.out.println(b2 + " after removing trailing zeros " + b4);
    }
}
Output:
785.000 after removing trailing zeros 785
125500 after removing trailing zeros 1.255E+5

Program 2:




// Program to demonstrate stripTrailingZeros() method of BigDecimal 
  
  
import java.math.*;
  
public class gfg {
  
    public static void main(String[] args)
    {
  
        BigDecimal b1 = new BigDecimal("785.00000");
        BigDecimal b2 = new BigDecimal("125500000");
  
        // Assigning the result of stripTrailingZeros method
        // to BigDecimal objects b3, b4
        BigDecimal b3 = b1.stripTrailingZeros();
        BigDecimal b4 = b2.stripTrailingZeros();
  
        // Printing b3, b4 values
        System.out.println(b1 + " after removing trailing zeros " + b3);
        System.out.println(b2 + " after removing trailing zeros " + b4);
    }
}
Output:
785.00000 after removing trailing zeros 785
125500000 after removing trailing zeros 1.255E+8
