Program: How to calculate exponent of the given number?


Description:

The exponential function is f(x) = ex. The Math.getExponent() method is used to get the x value of the given parameter, in which the parameter is a result of exponential function calculation.


Code:
package com.java2novice.math;

public class MyExponentEx {

	public static void main(String a[]){
		
		System.out.println("Exponent value of 15.0 is: "+Math.getExponent(15.0));
		System.out.println("Exponent value of 22.0 is: "+Math.getExponent(22.0));
		System.out.println("Exponent value of 65 is: "+Math.getExponent(65));
	}
}

Output:
Exponent value of 15.0 is: 3
Exponent value of 22.0 is: 4
Exponent value of 65 is: 6
