Hi - I'm just wondering if anyone knows what the last number in a floor function is for. [expr~ floor(($v1*8), 0)] works, but it doesn't seem to matter if the last number is 0 or 1 or whatever - it just rounds down to the nearest integer - am I missing something?

The manual states floor should have just one argument:

But apparently you need two. I don't know may it's a bug?

There's a manual? ...thanks!

Manual would be to much credit i guess. It is more like a reference.
