How do I calculate exponential function?

In mathematics, the exponential function is the function ex, where e is the number (approximately 2.718281828) such that the function ex equals its own derivative. The function f(x) = ex at the point x = 0 is equal to 1.

package org.kodejava.example.math;

public class ExponentExample {

    public static void main(String[] args) {
        double x = 0.0d;

        //
        // calculates e raised to the power of x (e^x)
        //
        double fx = Math.exp(x);

        //
        // calculates e raised to the power of x minus 1 (e^x - 1)
        //
        double fxm1 = Math.expm1(x);

        System.out.println("fx  = " + fx);
        System.out.println("fxm1= " + fxm1);
    }
}
