    Re: Magnetic Variation (Declination) Calculator
    From: Greg Rudzinski
    Date: 2009 Aug 4, 14:33 -0700

    Brad,
    
    Manoj C. Nair of NOAA University of Colorado responded to my email
    reguarding the zero result for 90� of latitude and said that the
    current program recognizes latitudes above 89.999 as undefined. The
    zero result must be a default number. I noticed another program glitch
    where 13� West declination was displayed as 167� East.
