Java.math.BigDecimal.movePointLeft() Method

Advertisements


Description

The java.math.BigDecimal.movePointLeft(int n) returns a BigDecimal which is equivalent to this one with the decimal point moved n places to the left. If n is non-negative, the call merely adds n to the scale. If n is negative, the call is equivalent to movePointRight(-n).

The BigDecimal returned by this call has value (this × 10-n) and scale max(this.scale()+n, 0).

Declaration

Following is the declaration for java.math.BigDecimal.movePointLeft() method

public BigDecimal movePointLeft(int n)

Parameters

  • n - number of places to move the decimal point to the left

Return Value

This method returns a BigDecimal which is equivalent to this one with the decimal point moved n places to the left

Exception

  • ArithmeticException - if scale overflows

Example

The following example shows the usage of math.BigDecimal.movePointLeft() method

package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

    public static void main(String[] args) {

        // create 4 BigDecimal objects
        BigDecimal bg1, bg2, bg3, bg4;

        bg1 = new BigDecimal("123.23");
        bg2 = new BigDecimal("12323");

        bg3 = bg1.movePointLeft(3); // 3 points left
        bg4 = bg2.movePointLeft(-2);// 2 points right

	String str1 = "After moving the Decimal point " + bg1 + " is " + bg3;
	String str2 = "After moving the Decimal point " + bg2 + " is " + bg4;

        // print bg3, bg4 values
        System.out.println( str1 );
        System.out.println( str2 );
    }
}

Let us compile and run the above program, this will produce the following result:

After moving the Decimal point 123.23 is 0.12323
After moving the Decimal point 12323 is 1232300
