Question

How to calculate power (base raised to the power exponent) in Java

Answer 1

package javaapplication1;

public class JavaApplication1 {
 
    public static void main(String[] args) {
        
        double d1 = 3.14;
        double d2 = 1.35;

        // double pow(double base, double exponent)
        System.out.printf("pow(%.3f, %.3f) = %.3f%n", d1, d2, Math.pow(d1, d2));
        
        double d3 = 2;
        double d4 = 3;
        
        // double pow(double base, double exponent)
        System.out.printf("pow(%.3f, %.3f) = %.3f%n", d3, d4, Math.pow(d3, d4));

    }
}
 
/*
run:

pow(3.140, 1.350) = 4.687
pow(2.000, 3.000) = 8.000
