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
