Lua math functions
Lua math functions

These are the functions in the "math" table.

Trigonometry functions use radians. To convert degrees to radians use math.rad.
Or, to look at it another way: 


radians = degrees * math.pi / 180


See also the "bc" (big number) library for functions that work with numbers to arbitrary precision.
