Re: [Chicken-hackers] [PATCH] random returns the same number on x86_64 all the time

Jim Ursetto scripsit:

Can't that be changed to at least make it the top 31 bits?  As it is,
if you look at the bottom 3 bits, say, to get a random number from 0
to 7, it will always be 0.  Shifting will solve that, but if you shift
too much because your code is moving from 64-bit Chicken to 32-bit,
the value will always be 0 once again.

This is why Common Lisp doesn't provide an interface giving you "a random
integer", only a random integer in the range 0 to n for a given n.
