The java.math.BigDecimal.scaleByPowerOfTen(int n) is an inbuilt method on java that returns a BigDecimal whose numerical value is equal to (this * 10n). The scale of the result is (this.scale() – n).
Syntax:
public BigDecimal scaleByPowerOfTen(int n)
Parameters:
The method accepts a single parameter n of integer type which refers to the value by which BigDecimal object is multiplied to power of ten.
Return value:This method returns the BigDecimal object of value this * 10n.
Below program illustrates the above mentioned method:
Program 1:
Java
// Java program to demonstrate the// scaleByPowerOfTen() methodimport java.math.*;public class Gfg { public static void main(String[] args) { // Assign two bigdecimal objects BigDecimal b1 = new BigDecimal("754.000"); BigDecimal b2 = new BigDecimal("75400"); // Assign the result of method on b1, b2 // to BigDecimal objects b3, b4 BigDecimal b3 = b1.scaleByPowerOfTen(4); BigDecimal b4 = b2.scaleByPowerOfTen(-4); // Print b3, b4 values System.out.println(b1 + " raised to power is " + b3); System.out.println(b2 + " raised to power is " + b4); }} |
Output:
754.000 raised to power is 7.54000E+6 75400 raised to power is 7.5400
Program 2:
Java
// Java program to demonstrate the// scaleByPowerOfTen() methodimport java.math.*;public class Gfg { public static void main(String[] args) { // Assign two bigdecimal objects BigDecimal b1 = new BigDecimal("200"); BigDecimal b2 = new BigDecimal("7540000000"); // Assign the result of method on b1, b2 // to BigDecimal objects b3, b4 BigDecimal b3 = b1.scaleByPowerOfTen(4); BigDecimal b4 = b2.scaleByPowerOfTen(-4); // Print b3, b4 values System.out.println(b1 + " raised to power is " + b3); System.out.println(b2 + " raised to power is " + b4); }} |
Output:
200 raised to power is 2.00E+6 7540000000 raised to power is 754000.0000
