How do I calculate a random integer between n and p, inclusively?
Thanks

#declare RSeed = seed(1);
#declare RandomNumber = n + rand(RSeed) * (p - n);

That results in a float, not an integer.

floor( rand(R)*((p-n)+1) + 0.5 )
should do the trick

... provided you figure out that you need to add n ;)
Oops.

Yes, there are two functions to convert a float to a close-by integer:
1. Floor
If the float is, let's say, "11.4676475" (could be a multiplication of a
"rand" random result), floor returns "11" (the next integer BELOW that
float).
2. Ceil(ing)
If the float is, let's say, "11.4676475" (could be a multiplication of a
"rand" random result), floor returns "12" (the next integer ABOVE that
float).

Why not this: int(RRand(n,p,R))

RRand(Min,Max,RandSeededStream) from rand.inc. To get the inclusive part
of the request I think we need:
int(RRand(n,p+(1-1e-6),R))
or
floor(RRand(n,p+(1-1e-6),R))
