Angles
Angles can be specified either in degrees or in radians, by selecting Degrees or Radians in the Options menu.
When angles are specified as degrees, they may be entered in the form of
degrees, minutes, and seconds by using the format d:m for
degrees and minutes, or d:m:s for degrees, minutes, and
seconds.
For example, 10 degrees 2.4 minutes can be entered as 10:2.4,
which is evaluated to 10.04 degrees.
