How to enter whole degrees and decimal minutes ?

[springer5]

Hi

Does anyone know of a way to enter whole degrees and decimal minutes on the HP Prime?


For example, to calculate....

12 degrees and 35.67 minutes plus 24 degrees and 18.553 minutes.


I'm trying to use my Prime for marine navigational formulae and all the data is presented in this format. the degrees,minutes,seconds button on the Prime only accepts whole numbers of each.

I can of course convert it all to decimal degrees but that's a pain when the formulae are quite complex and each new set of numbers needing to be entered is based on the previous step's results. It means I'm converting in the middle of formula entry which is very cumbersome and prone to error.


Anyone know of a way?


Thanks in advance
