Real Number Functions
Some functions can only use real numbers as arguments. Among these
are angle conversions, percentages, and several functions that round,
truncate, or extract parts of real numbers.
Angle Conversion Functions
Two commands in the MTH REAL menu convert values between
decimal degrees and radians. Two other commands in the TIME
menu let you do degrees-minutes-seconds calculations using
hours-minutes-seconds (HMS) format.
In Degrees mode, angle arguments and results use decimal degrees.
