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.
