BigDecimal pow() method in Java with Examples

The java.math.BigDecimal.pow(int n) method is used to calculate a BigDecimal raise to the power of some other positive number passed as parameter (this)n. This method performs raises this BigDecimal number to the power of the positive number passed as the parameter.

Syntax:

public BigDecimal pow(int n)

Parameters: This method accepts a parameter n which is the exponent to which we want to raise the power of BigDecimal number.

Returns: This method returns a BigDecimal which is equal to (this)n.

Exception: The parameter n must be in the range 0 through 999999999, inclusive otherwise ArithmeticException is thrown

Below programs illustrate the pow() method of BigDecimal class

// Java program to demonstrate
// pow() method of BigDecimal
  
import java.math.BigDecimal;
  
public class GFG {
    public static void main(String[] args)
    {
        // Creating BigDecimal object
        BigDecimal b1
            = new BigDecimal("924567");
  
        // Exponent or power
        int n = 5;
  
        // Using pow() method
        BigDecimal result = b1.pow(n);
  
        // Display result
        System.out.println("Result of pow operation "
                           + "between BigDecimal "
                           + b1 + " and exponent "
                           + n + " equal to "
                           + result);
    }
}

Output:

Result of pow operation between BigDecimal 924567 and exponent 5 equal to 675603579456764176151564447607
