Hi;
The functions [->RAD] ([SHIFT][-]) and [->DEG] ([SHIFT][+]) are used to convert from readians ->DEGrees and from degrees ->RADians. Angles in degrees to be converted to radians must be entered as decimal values, not minutes-seconds. If you want to find the radians equivalent to 21 degrees and 30 minutes, you should input 21.5 (21 degrees and half degree) instead of 21.3.
Anyway, you can also convert from degres.minutes-seconds to decimal degrees with [->H] ([SHIFT][1/X]) and vice-versa with [->HMS] (([SHIFT][yX]).
Try this: 21.3 [SHIFT][1/X] (->H) Display: 21.5000
Best regards.
