    Re: Magnetic Variation (Declination) Calculator

    Hi Greg
    I just entered the pole for a gee-wiz kind of exercise.  To my surprise, it 
    returned zero, so I tried a location close to the pole.  That returned 
    non-zero, indicating that the software has some sort of bug.
    Since I have no way to verify any other result it may present to me, I will 
    distrust the data.  How many other lat long locations give 'bad' data?  How 
    would I know?
    Should NOAA fix this?  Certainly. How silly of them to permit an entry which provides erroneous results.
    Do navigators depend exclusively on a compass within 366 feet of the north pole?  I sure hope not...
    Best Regards

    It looks like values above 89.998996� of latitude are all zero instead
    of 14� 24'W. Does NOAA need to correct this since it is only 366 ft
    from the pole?
