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

Usage

From source file:Power.java

public static void main(String[] args) {
    System.out.println(Math.pow(2, 2));
}

From source file:Main.java

public static void main(String[] args) {
    // returns 2 raised to 2, i.e. 4
    System.out.println(Math.pow(2, 2));
    // returns -3 raised to 2, i.e. 9
    System.out.println(Math.pow(-3, 2));
}

From source file:MainClass.java

public static void main(String args[]) {
    System.out.println(Math.pow(2, 12));
}

From source file:Main.java

public static void main(String[] args) {
    double x = 1.2;
    double y = 5.4;

    // print x raised by y and then y raised by x
    System.out.println("Math.pow(" + x + "," + y + ")=" + Math.pow(x, y));
    System.out.println("Math.pow(" + y + "," + x + ")=" + Math.pow(y, x));

}

From source file:MainClass.java

public static void main(String[] args) {
    // Display the square root of 2 using sqrt()

    System.out.println(Math.sqrt(2.0));
    // Calculate and display using pow()
    System.out.print("pow(2.0, 0.5) = ");
    System.out.println(Math.pow(2.0, 0.5));
    System.out.println();//from  w  w w .  j a  v  a 2  s.  c o m
