Document

Returns a BigDecimal which is numerically equal to this one but with any trailing zeros removed from the representation.

Usage

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg1 = new BigDecimal("235.000");
    BigDecimal bg2 = new BigDecimal("23500");

    // assign the result of stripTrailingZeros method to bg3, bg4
    BigDecimal bg3 = bg1.stripTrailingZeros();
    BigDecimal bg4 = bg2.stripTrailingZeros();

    String str1 = bg1 + " after removing trailing zeros " + bg3;
    String str2 = bg2 + " after removing trailing zeros " + bg4;

    // print bg3, bg4 values
    System.out.println(str1);// w  ww .  java2 s .com
    System.out.println(str2);
}
