    Declaration

    public static int floorlog2(int x);

    Parameters

    Parameter Description
    x Integer to be used as input.

    Returns

    int Floor of base-2 logarithm of x.

    Description

    Computes the floor of the base-2 logarithm of x.

    x must be greater than zero, otherwise the result is undefined.
