Degree, Minute, Second (Sexagesimal) Calculations
Performing an addition or subtraction operation between sexagesimal values,
or a multiplication or division operation between a sexagesimal value and a
decimal value will cause the result to be displayed as a sexagesimal value.
You also can convert between sexagesimal and decimal. The following
is the input format for a sexagesimal value: {degrees} $ {minutes} $
{seconds} $.
Note: You must always input something for the degrees and minutes, even
if they are zero.
