Note that the degree and minute entries must be integers,
and the minute and second entries must be positive.
Decimals are not allowed, except in the seconds.
Note too that the HP
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″
2
, the whole value is squared, not just
the seconds component. The result in this case is
108°39′ 26.8544″ .
