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

該方法的返回類型為BigDecimal ，它返回一個與該BigDecimal相似的BigDecimal，但沒有任何尾隨零。

Example:

例：

// Java program to demonstrate the example // of BigDecimal stripTrailingZeros() method of BigDecimalimport java.math.*;public class StripTrailingZerosOfBD {public static void main(String args[]) {// Initialize two variables - double and // String typedouble 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 removedBigDecimal 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 digitsbd = b_dec2.stripTrailingZeros();System.out.println("b_dec2.stripTrailingZeros(): " + bd);} }

Output

輸出量

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