more information on programming in Lua, please see

There are a few exceptions/additions to the Lua support in Rockbox:
No floating point support.
The number type in Lua is usually float, however in the
Rockbox implementation it is integer.
Non-supported libraries.
The coroutine, debug and math libraries are not supported.
Partially-supported libraries.
The os and package libraries are only partially supported.
Additional libraries.
The bitlib library is integrated to support bitwise operators. See

and
http://lua-users.org/wiki/BitwiseOperators
Documentation of the API is still a work in progress, and the API itself is not finalised.
