double EdgeArcCircle::getAbsoluteAngleOfNormalizedVect ( double  ux,
double  uy 
) [static]

Given a normalized vector defined by (ux,uy) returns its angle in ]-Pi;Pi]. So before using this method ux*ux+uy*uy should as much as possible close to 1. This methods is quite time consuming in order to keep as much as possible precision. It is NOT ALWAYS possible to do that only in one call of acos. Sometimes call to asin is necessary due to imperfection of acos near 0. and Pi (cos x ~ 1-x*x/2.)
