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
