java.math.BigDecimal.stripTrailingZeros()是Java中的一種內置方法,該方法返回一個BigDecimal,其數值與該數字相等,但從表示形式中刪除了所有尾隨零。因此,本質上,該函數從BigDecimal值中減去尾隨的零。
用法:
public BigDecimal stripTrailingZeros()
參數:此方法不接受任何參數。
返回值:此方法返回一個等於BigDecimal的數值,並刪除所有尾隨零。
例子:
Input: 785.000 Output: 785 Input: 125500000 Output: 1.255E+8
以下示例程序旨在說明上述方法的用法方式:
示例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);
}
}
輸出:
785.000 after removing trailing zeros 785 125500 after removing trailing zeros 1.255E+5
示例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);
}
}
輸出:
785.00000 after removing trailing zeros 785 125500000 after removing trailing zeros 1.255E+8
