I recently made the switch from TI-Basic to Axe, but was very disappointed when I realised that I can't use some of my favourite commands such as fPart( (which I used to use all the time for data compression), iPart( and angle commands such as R>Pr.

Why is this and will they be useable in the future?

P.S Since the fPart and iPart commands can't be used, how would I go about getting the integer and decimal parts of numbers? This functionality is VERY important for the game I'm making.
