Hi,

I noticed that the Fusion 8 manuals (user, tool, scripting) don't have all math expressions covered, at least ceil and floor are missing. Is there a complete list of the expressions somewhere?

Hey - I have never found a full list, but what I tend to do is to look up LUA syntax and in a lot of cases this will work out of the box. For instance:

Which expressions? If it's scripting, then there's the issue of Fusion supporting 3+ scripting languages. The thought over many years is that the docs shouldn't teach you Lua or Python or Cg or OpenCL or whatever, they should just tell you about the interfaces and any proprietary functions or libs.

Not for scripting, just when using expressions. For example I can use math.ceil and math.floor, but those are nowhere in the manuals, so I was just wondering what else is not there...

It's just Lua.

Got it, thanks Okke and Chad!
