float2::AngleBetween
Syntax
float float2::AngleBetween(const float2 &other) const; [4 lines of code]Returns the angle between this vector and the specified vector, in radians.
Note
This function takes into account that this vector or the other vector can be unnormalized, and normalizes the computations. If you are computing the angle between two normalized vectors, it is better to use AngleBetweenNorm().
