Floating-point weirdness with vectors
shBLOCK opened this issue · 4 comments
Multiplying a vector with a negative number causes its 0 elements to turn to -0:
Comparing (0,0,0)==(-0,-0,-0) works fine (returns 1)
But it doesn't seem to be working well with the Set operations, it thinks (0,0,0) != (-0,-0,-0): (here the XOR operation should think they're the same and return an empty list)
This causes my spell to only work in +x,+y and +z axis.
Ah yep that's an easy fix, which I will do tomorrow.
