Floating point behaviour is common to most programming languages, what
does this have to do with lua?

That's true. However, the question is asked often on the list, which warrants a FAQ entry, by definition. 

I joind the list in February of this year, and I've found 4 occurrences of newbie questions related to floating point arithmetics.

"Floating Point inaccuracies"

"math.floor and rounding"

"Why do some math functions return -0"

"not all numbers are treated the same way"
