Time, Decimal and Sexagesimal Calculations
Conversion between decimal and sexagesimal numbers can be performed,
and, while using sexagesimal numbers, also conversion to seconds and
minutes notation. The four basic arithmetic operations and memory calcula-
tions can be performed using the sexagesimal system. Notation for
sexagesimal is as follows:
