How to enter whole degrees and decimal minutes ?

[ijabbott]

This is probably a can of worms, but it would be nice if the Prime at least accepted DDM (degrees decimal minutes) format on input, even if it then automatically converted it to DMS, which doesn't sound too hard to do. Displaying the results in DDM format would be a whole separate can of worms though!

(For what it's worth, Casio scientific calculators allow input in DD, DDM or DMS format, but can only display results in DD or DMS format.)
