Prerequisite : BigDecimal Basics
The java.math.BigDecimal.movePointRight(int n) method is used to move the decimal point of the current BigDecimal by 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 method has value (this × 10n) and scale max(this.scale()-n, 0).
Syntax:
public BigDecimal movePointRight(int n)
Parameter: The method takes one parameter n of integer type which refers to the number of places by which the decimal point is required to be moved towards the right.
Return Value: The method returns the same BigDecimal value with the decimal point moved n places to the right.
Exception: The method throws an ArithmeticException if the scale overflows.
Examples:
Input: value = 2300.9856, rightshift = 3
Output: 2300985.6
Explanation:
After shifting the decimal point of 2300.9856 by 3 places to right,
2300985.6 is obtained.
Alternate way: 2300.9856*10^(3)=2300985.6
Input: value = 35001, rightshift = 2
Output: 3500100
Below program illustrate the movePointRight() method of BigDecimal:
import java.math.*;
public class GFG {
public static void main(String[] args)
{
BigDecimal bigdecimal = new BigDecimal( "2300.9856" );
int i = 3 ;
BigDecimal changedvalue = bigdecimal.movePointRight(i);
String result = "After applying decimal move right
by move Distance " + i + " on " + bigdecimal +
" New Value is " + changedvalue;
System.out.println(result);
}
}

Output:
After applying decimal move right by move Distance 3 on 2300.9856 New Value is 2300985.6
