Java.math.BigDecimal.movePointRight() Method

Description

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

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

Declaration

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

```public BigDecimal movePointRight(int n)
```

Parameters

n − Number of places to move the decimal point to the right.

Return Value

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

Exception

ArithmeticException − If scale overflows.

Example

The following example shows the usage of math.BigDecimal.movePointRight() 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.movePointRight(3); // 3 places right
bg4 = bg2.movePointRight(-2);// 2 places left

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 123230
After moving the Decimal point 12323 is 123.23
```
