BigDecimal Class stripTrailingZeros() method

  • stripTrailingZeros() method is available in java.math package.
  • stripTrailingZeros() method is used to get a BigDecimal that is equivalent to this BigDecimal but without any Trailing zeros.
  • stripTrailingZeros() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • stripTrailingZeros() method does not throw an exception at the time of trailing zeros.

Syntax:

    public BigDecimal stripTrailingZeros();

Parameter(s):

  • It does not accept any parameter.

Return value:

The return type of this method is BigDecimal, it returns a BigDecimal that is similar to this BigDecimal but without any trailing zeros.

Example:

// Java program to demonstrate the example 
// of BigDecimal stripTrailingZeros() method of BigDecimal

import java.math.*;

public class StripTrailingZerosOfBD {
    public static void main(String args[]) {
        // Initialize two variables - double and 
        // String type
        double val = 1234521.000;
        String str = "1211000";

        // Initialize three BigDecimal objects  
        BigDecimal b_dec1 = new BigDecimal(val);
        BigDecimal b_dec2 = new BigDecimal(str);

        // returns this BigDecimal (b_dec1) but
        // with removed any trailing zeros i.e. 1234521.000
        // it returns 1234521 because traling zeros will be removed
        BigDecimal bd = b_dec1.stripTrailingZeros();
        System.out.println("b_dec1.stripTrailingZeros(): " + bd);

        // returns this BigDecimal (b_dec2) but
        // with removed any trailing zeros i.e. 1211000
        // it returns 1.211E+6 and after decimal represent 6 digits
        bd = b_dec2.stripTrailingZeros();
        System.out.println("b_dec2.stripTrailingZeros(): " + bd);
    }
}

Output

b_dec1.stripTrailingZeros(): 1234521
b_dec2.stripTrailingZeros(): 1.211E+6
