Time, Decimal and Sexagesimal Calculations
This calculator performs decimal-to-sexagesimal conver-
sion and sexagesimal-to-decimal conversion. In addition,
the four basic arithmetic operations and memory calcula-
tions can be carried out using the sexagesimal system.
Notation for sexagesimal is as follows:
123.404080
degree second
minute
Note: When the calculation or conversion result is con-
verted, a residual may occur.
