Thank you very much for your feedback and the link to those libraries and tools. I will try the math one as well.

For random number generation using the uniform distribution Lua has a built-in function math.random. See also math.randomseed.

Lua's math.random uses the random number generator provided by the C library.
Historically, this generator was not very good, but in recent C libraries, e.g. the GNU C library, this generator is much better. If you need to make sure you're using a better random number generator, try my lrandom at which uses the Mersenne Twister.
