using double instead of float

[SauerkrautChang]

Hello, I was following your video and decided to use doubles instead of floats. Using doubles instead of floats creates a weird artefact in the manifestation of the cube, there is a sort of wall blocking the lower half of the cube, and it slightly glitches up and down the y axis. I was wondering if you know the reason for this? I know doubles are 64bits while floats are 32bits, but what goes on in the code to produce such a difference in the cube when using one over the other?
