A simple degree-minutes(fractions) add/subtract calculator.
This is written for celestial navigation using tables. The features are
- support degrees in degree and minutes, with minutes as a fraction, eg. 30°02'3
- support time as hours-minutes-seconds, eg. 10h20m03
- add/subtract
- division by integer for averaging observations
It was also for me to experiment with and try learning some Swift and SwiftUI.
Todo
- unit tests for DegreeCore
- unit tests for ModelData's functions
- treat op without input as ANS
Bugs
- disallow > 3 ints for degrees when typing
- if entering 600'0, it displays 0d00'0 instead of 10d00'0
