product ? *** and sum ? ***

[Helge Gabert]

I just ran into this - -

in Home: product(N,N,1,3,.5) runs fine

But product(N,N,.5,3,.5) does not run and returns the arguments as multiplicands.

in CAS: product(n,n,1,3,1/2) runs fine

But again, product(n,n,1/2,3,1/2) returns 3/4*n^2.

It appears that the minimum value is not to be less than one, which is strange.
