Comment #5 on issue 3617 by [email protected]: Impossible to work with
floating point numbers in the geometry module
http://code.google.com/p/sympy/issues/detail?id=3617
I vote for solving this issue!
I wrote program for clipping (computer graphics lab). It ran very slow (7
seconds for clipping 10 lines with rectangle!). I spent several hours
trying to understand what is wrong with my code. Then I ran profiler and
saw that almost all time is wasted on __new__ from Point class (nsimplify
function to be precise). I googled and found this issue. After I change
defaults (if kwargs.get('evaluate', False):) my program started to run very
fast, as it supposed to be.
I attach profiles and screenshots of RunSnakeRun profiler.
