renoise random algorithms

i am interested in renoise random algorithms in random lfo and randomize automation
i use these a lot
can you tell me in brief what algorithms or what technique is used to produce random values?
thanks

:D

internally we use an approximation of a pseudo-random uniform distribution, that is similarly how the C99 rand() function works.

thanks.

i was starting to think i should start looking for the dice inside my computer :P
