Calculator Compatibility

This command requires a TI-89 Titanium or Voyage 200 calculator with AMS version 3.00 or higher.

The ▶Rad command is used to convert both degrees and gradians into radians. (If the command is given a value in radians it returns that value unchanged).

If you do not specify what unit you want to be used (using either the r command, the ° command, or the G command), whatever default the calculator's mode is set to will be used. Here are some examples:

:setMode("ANGLE", "DEGREE")
:90▶Rad
           1
:90^r▶Rad
           90

It appears to be equivalent to the ^r command, but only on the TI-89 Titanium or Voyage 200.
