DMS).
To set the Angle mode for any part of an entry:
Select the Angle mode. Entries are interpreted and results displayed according to the Angle mode, or
Select a unit modifier ( 
) for any part of an entry. Entries with unit modifiers are interpreted accordingly, overriding the Angle mode.
To convert an entry:
