If you are aiming to write general purpose NMEA parsing code, I 
recommend you prepare your code to accept 1-3 digits for degrees and 1-6 
digits for minute decimals. Integer minutes are always 2 digits, zero 
padded if necessary. The great majority of NMEA producing devices 
zero-pad the degrees value, but I have seen some that don't do that. The 
number of minute decimals varies typically between 2 and 4, but it 
doesn't hurt if you prepare for something between 1 and 6 at least.
