[Visualpython-users] mag2()

[Arthur S. <aj...@ix...>]

I am refactoring some code, focusing on performance
issues.

And find it quite common in my code  to be calculating the squared
length of a vector.

A look at cvisual finds mag2() already there as the underlying function
for mag(), but it is not exposed to Python.  

So in doing mag(vector)**2 I am essentially calculating a
square root(in C) and then squaring it (in Python).  Unpretty.

I did the trivial work to expose mag2 as a Python function, and
am using it, and hoping the change could be made in the "official"
distribution
