Java bigdecimal pow 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.
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)
BigDecimal objects with names x & y;
y = x.pow(n);
Java_bigdecimal_pow.java
import java.math.BigDecimal;
public class Java_bigdecimal_pow {
public static void main(String args[]) {
int i = 2;
double d = 3;
BigDecimal rose = new BigDecimal(i),
jack = new BigDecimal(d);
System.out.println("rose object value :" +
" " + rose);
System.out.println("method generated " +
"result : " + rose.pow(3));
System.out.println("\njack object value " +
": " + jack);
System.out.println("method generated " +
"result : "
+ jack.pow(4).floatValue());
}
