public class MathDemo
{

    public static void main(String[] args)
    {

        double x = 5.65;
        double y = 16.12;

        /*
         * Math.E, which is the base of natural logarithms.
         */
        System.out.printf("The value of " + "e is %.4f%n", Math.E);


        /*
         * Returns the base of the natural logarithms, e, to
         * the power of the argument.
         */

        System.out.printf("exp(%.3f) " + "is %.3f%n", x, Math.exp(x));

        /*
         * Returns the natural logarithm of the argument.
         */

        System.out.printf("log(%.3f) is " + "%.3f%n", x, Math.log(x));

        /*
         * Returns the value of the first argument raised to
         * the power of the second argument.
         */

        System.out.printf("pow(%.3f, %.3f) " + "is %.3f%n", x, y,
                Math.pow(x, y));

        /*
         * Returns the square root of the argument.
         */
        System.out.printf("sqrt(%.3f) is " + "%.3f%n", x,
                Math.sqrt(x));
    }
}
Output
The value of e is 2.7183
exp(5.650) is 284.291
log(5.650) is 1.732
pow(5.650, 16.120) is 1327458579845.300
sqrt(5.650) is 2.377
