Well, when I type "-1**2" into Python, it returns -1. If I run "1**2 + -1**2" it returns 0. So, is there a bug in Python then? Running 2.6.6 on Ubuntu 10.10.
Removing the if statement from get_angle fixed the angle problem for me, because of this. On Sat, 23 Jul 2011 13:56 +0200, "DR0ID" <dr...@bluewin.ch> wrote: Your mistake basically was that you assumed that -1 ** 2 == -1 which is not.
