Returns f × 2 ^scaleFactor rounded as if performed by a single correctly rounded floating-point multiply to a member of the float value set.

Usage

From source file:Main.java

public static void main(String[] args) {

    // Returns 12.0 x (2^3)
    double scalbResult = Math.scalb(12.0, 3);
    System.out.println("Math.scalb (12.0, 3) = " + scalbResult);

}

    // calculate x multiplied by 2 raised in y
    System.out.println("Math.scalb(" + x + "," + y + ")=" + Math.scalb(x, y));
