Hi,

I know you can perform the basic operations + - / and * in celX, however is it possible to access math libraries to perform more advanced scientific math within a celX script?
I haven't seen any documentation of this anywhere, however in looking at some of the things being done with Lua, I'm almost sure this must be possible, but perhaps undocumented.
Can someone enlighten me?

The functions I would like to use are all the usual suspects:

log10,
ln (natural logarithm),
pi(),
cos, sin, tan,
acos, asin, atan,
e,
y^x,
sqrt,
...etc

Yes, it's possible: simply use the namespace math
For example:
math.pow(),
math.tan(),
math.sin(), etc.

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

Thanks guys. That's very helpful and has covered everything I need to do (for now anyway )
