2D vector Math

[oli_lab]

Hi !

is there a way to easilly do math directly on 2D vectors ?

for exemple multiply a vector by a scalar, add two vectors, normalize a vector ?

or should I do my own fonctions ?

thanx

Sounds like you want Eigen - http://eigen.tuxfamily.org/index.php?title=Main_Page

I have doubts : should I use float or long ?

try with float before all,

but it really depends of the purpose,
until your computation need long because of intermediate approximation and precision limit of the float format. but you'll know that only by trying with float before

if it's 'only' to visually rotate a bunch of vectors, i don't see the need and extra memory of long.
DSP computation is another story and can benefit of long for intermediate result, even if the final number will be a float (as usine TPrecision is a float for now).
