let's say I have a value that is between 0 and 1. I have a grid size and would like the value to snap to grid. so if grid size is equal to two I would like to switch from 0 to 1 if grid size equal to three this would switch from 0, 0.5 to 1 if it's four 0, 0.33, 0.66, 1 and so on...

Assuming the language you use has a round function that rounds to the nearest integer, and calling v the value and n the grid size:

round(v * (n-1)) / (n-1)
