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

You also can convert between sexagesimal and decimal. The following
is the input format for a sexagesimal value: {degrees}
$
{minutes}
$
{seconds}
