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:
