Java bigdecimal pow method example

     

Example below demonstrates working of bigdecimal class pow method. Method returns a bigdecimal value (to the power n) i.e. (this.object )(to the power n) as per context settings.

In short method returns a bigdecimal value that is the product of this.object (in which the method is invoked) to n number of times with itself.

Method throws NumberFormatException if it finds value other than integer or double and throws ArithmeticException if the rounding mode is UNNECESSARY. 

Syntax for using the method : public BigDecimal pow(int n, mc)
BigDecimal objects with names x & y;
y = x.pow(n, mc);

import java.math.BigDecimal;
import java.math.MathContext;

public class Java_bigdecimal_pow_example {
  public static void main(String args[]) {

  short i = 5;
  float d = 9;

  MathContext mc = new MathContext(0);
  mc = mc.DECIMAL32;

  BigDecimal live = new BigDecimal(i), tech = new BigDecimal(d);
  System.out.println("live object value : " + live);
  System.out.println("method generated result : " + live.pow(2));

  System.out.println("\ntech object value : " + tech);
  System.out.println("method generated result : "
  + tech.pow(2).floatValue());

  }
}
