syntax

Hello, advise someone where to find the syntax of the language used in the Fusion? (Mathematical function). Thank you

You can fid the Lua Math Functions here:

http://lua-users.org/wiki/MathLibraryTutorial

And the complete manual here:
http://www.lua.org/manual/5.3/

The Scripting Guide and the scripting reference can be found here:

I thought .....that Python is implemented in Fusion

Thanks

Yes. From the manual:

Fusion has two scripting Languages to choose from: Lua and Python. Both access the same API through FusionScript so it is up to you which language to choose.

python can be used with fusion, but you need to have it installed on your pc. its not included in fusion.

but AFAIK you cant use python in the simple expressions
