        ' radians multiply degrees by 180/Math.PI) and returns the hyperbolic
        ' cosine for the angle as a double data type.

        '  
        ' Parameter1: doublenumber - double percision floating point 
        ' number representing an angle measured in radians. 
        '
        ' Result: double - represents the hyperbolic cosine of the angle 
        ' specified in parameter1. If parameter1 is 
        ' is equal to NegativeInfinity or PositiveInfinity, 
        ' PositiveInfinity is returned. If parameter1 
        ' is equal to NaN, NaN (Not a Number) is returned.
