RAND() Algorithm
PostPosted: Wed Mar 25, 2009 12:15 pm     Reply with quote
Does anyone know the algorithm CCS uses for its rand() pseudo random number generator?

Also, stdlib.h defaults the RAND_MAX to 32767. Is this the maximum allowed value?

Currently using CCS version 4.084.

Thanks.

The source code for the function is in stdlib.h. Just search for this line
near the end of the file and you'll see the code:
