Returns the correctly rounded positive square root of a double value.

Usage

From source file:Main.java

public static void main(String[] args) {
    double d = Math.sqrt(-10);
    boolean b1 = Double.isNaN(d);

    System.out.println(b1);/*from  ww  w.  j  ava2  s.c  o m*/

    Double dObj = new Double(d);
    boolean b2 = dObj.isNaN();
    System.out.println(b2);

}

From source file:Main.java

public static void main(String[] args) {
    float f = (float) Math.sqrt(-10);
    boolean b1 = Float.isNaN(f);
    System.out.println(b1);/*from www.j  a v a2  s.co m*/

    Float fObj = new Float(f);
    boolean b2 = fObj.isNaN();
    System.out.println(b2);
}

From source file:Main.java

public static void main(String args[]) {

    // c is dynamically initialized
    double c = Math.sqrt(2 * 2);

    System.out.println("c is " + c);
}

From source file:Main.java

public static void main(String[] args) {
    // returns square root of 9, i.e. 3
    System.out.println(Math.sqrt(9));
    // returns square root of 25.5
    System.out.println(Math.sqrt(25.5));
}

From source file:MainClass.java

public static void main(String args[]) {
    System.out.println(Math.sqrt(10));
}

From source file:MainClass.java

public static void main(String[] args) {
    // Display the square root of 2 using sqrt()
    System.out.print("sqrt(2.0) = ");
    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();/* www.  j av  a2s. c  o  m*/
}

From source file:Main.java

public static void main(String[] argv) throws Exception {

    for (double i = 1.0; i < 20.0; i++)
        System.out.printf("%10.2f %10.2f %10.2f\n", i, Math.sqrt(i), i * i);

}

From source file:Main.java

public static void main(String[] args) {

    double x = 9;
    double y = 25;

    // print the square root of these doubles
    System.out.println("Math.sqrt(" + x + ")=" + Math.sqrt(x));
    System.out.println("Math.sqrt(" + y + ")=" + Math.sqrt(y));

}

From source file:TrigSolv.java

    // Apllying Pythagoras' Theorem
    // Obtain sides from user
    System.out.println("Side c in terms of sides a and b");
    a = 10d;/*  w  w  w  . j av  a  2 s  . c  om*/
    b = 20d;
    c = Math.sqrt((a * a) + (b * b));
    System.out.println("Side c = " + c);

    // Using side/angle formula
    System.out.println("Side c in terms of side b and angle A");
