BigDecimal movePointLeft() Method in Java
prerequisite : BigDecimal Basics
The java.math.BigDecimal.movePointLeft(int n) method is used to move the decimal point of the current BigDecimal by 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 value returned by this method has value (this × 10-n) and scale max(this.scale()+n, 0).
Syntax:
public BigDecimal movePointLeft(int n)
Parameter: The method takes one parameter n of integer type which refers to the number of places the decimal point is required to be moved towards the left.
Return Value: The method returns the same BigDecimal value with the decimal point moved n places to the left.
Exception: The method throws an ArithmeticException if the scale overflows.
Examples:
Input: value = 2300.9856, Leftshift = 3
Output: 2.3009856
Explanation:
while shifting the decimal point of 2300.9856
by 3 places to the left, 2.3009856 is obtained
Alternate way: 2300.9856*10^(-3)=2.3009856
Input: value = 35001, Leftshift = 2
Output: 350.01
Below program illustrate the movePointLeft() 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.movePointLeft(i);
String result = "After applying decimal move left by move Distance "
+ i + " on " + bigdecimal + " New Value is " + changedvalue;
System.out.println(result);
}
}
|
Output:
After applying decimal move left by move Distance 3 on 2300.9856 New Value is 2.3009856
