[SOLVED] HAngle doesn't work in latest (14603) firmware?

[Joe Horn]

HAngle only returns the GLOBAL angle setting, not the current APP's angle setting, which overrides the global setting. Either press Shift Symb (Setup) to see your current app's angle setting, or evaluate the AAngle system variable. When AAngle is set to anything other than 0 ("System"), then HAngle will return a value which might not correspond to the current angle setting which is now controlled by AAngle.

This is usually noticed by people for the first time when they try the Triangle Solver app, whose AAngle is Degrees by default. As long as that app is the current app, and until the user presses Shift Symb and changes the app's angle mode to System, the value of HAngle will not change when the Shift Settings angle mode is changed.

Bottom line: ALWAYS make sure that the Shift Symb angle mode is set to "System". Then (and only then) will the HAngle value be reliable.

Mini-challenge: What math expression, using both HAngle and AAngle, will always return the correct current angle setting?
