Note that the degree and minute entries must be integers,
and the minute and second entries must be positive.

Prime treats a value in
hexgesimal format as a
single entity. Hence any
operation performed on
a hexagesimal value is
performed on the entire
value. For example, if
you enter 10°25′ 26″

the seconds component. The result in this case is
108°39′26.8544″.
