Java.math.BigDecimal.scaleByPowerOfTen() Method
Description
The java.math.BigDecimal.scaleByPowerOfTen(int n) returns a BigDecimal whose numerical value is equal to (this * 10n). The scale of the result is (this.scale() - n).
Declaration
Following is the declaration for java.math.BigDecimal.scaleByPowerOfTen() method.
public BigDecimal scaleByPowerOfTen(int n)
Parameters
n − Value by which BigDecimal object is multiplied to power of ten.
Return Value
This method returns the BigDecimal object of value this * 10n.
Exception
ArithmeticException − If the scale would be outside the range of a 32-bit integer.
Example
The following example shows the usage of math.BigDecimal.scaleByPowerOfTen() 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("235.000"); bg2 = new BigDecimal("23500"); // assign the result of method on bg1, bg2 to bg3, bg4 bg3 = bg1.scaleByPowerOfTen(3); bg4 = bg2.scaleByPowerOfTen(-3); String str1 = bg1 + " raised to 10 power 3 is " +bg3; String str2 = bg2 + " raised to 10 power -3 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 −
235.000 raised to 10 power 3 is 235000 23500 raised to 10 power -3 is 23.500
