Depends how huge they are. Pick 1000000032. That should give 312 degrees, 
supposing you use [wrap 0 360] instead of [wrap 0 359]. But as a pd float, 
it gives either 280 or 344 depending on how the rounding happens.

But this [wrap] trick is definitely not something that one can consider 
using if one is concerned with gimbal lock, and pspunch said he wants to 
avoid gimbal lock, so I don't know why you even mention it, if you want so 
much to stick to the "heart of the question".
