Old method: why "Xmouse/32*32" works?

[Blizna]

I have found old file with this method used to snap object to pseudo grid.

Im just curious why does it work? Thanks

Because MMF use integers by default. Integers doesn't have decimals, and that's why it will snap.

If you include a decimal in the calculation, the values are converted to float values, which allows decimals.

Integers:

35 / 32 = 1
78 / 32 = 2

When we multiply again with 32 we get the "snap".

1 * 32 = 32
2 * 32 = 64

And that's why:

35 / 32 * 32 = 32
78 / 32 * 32 = 64


Float:

35 / 32.0 = 1.09
78 / 32.0 = 2.44

If wwe multiply with 32 now, it will ofcourse not snap to the grid.

Try Xmouse/32.0*32 and it will not snap.
215/32 = 6
215/32.0 = 6.71875
