BigDecimal类stripTrailingZeros()方法 (BigDecimal Class stripTrailingZeros() method)

• stripTrailingZeros() method is available in java.math package.

  stripTrailingZeros()方法在java.math包中可用。

• stripTrailingZeros() method is used to get a BigDecimal that is equivalent to this BigDecimal but without any Trailing zeros.

  stripTrailingZeros()方法用于获取与该BigDecimal等效但没有任何尾随零的BigDecimal。

• 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()方法是一种非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。

• stripTrailingZeros() method does not throw an exception at the time of trailing zeros.

  在尾随零时， stripTrailingZeros()方法不会引发异常。

Syntax:

句法：

    public BigDecimal stripTrailingZeros();

Parameter(s):

参数：

• It does not accept any parameter.

  它不接受任何参数。

Return value:

返回值：

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

该方法的返回类型为BigDecimal ，它返回一个与该BigDecimal相似的BigDecimal，但没有任何尾随零。

Example:

例：

// 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

输出量

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