float point and why it is used in factorio

[featherwinglove]

And so long as the float library used is consistent across platforms, it won't be the cause of any kinds of miscalculations (to be honest, doesn't the server do it all for everyone anyway?).

No it doesn't, every client does all the exact same calculations and everyone needs to agree on the result down to the last least-significant bit.

It was annoying enough way back when. Another CPU bug like this one could render Factorio multiplayer nigh impossible.
