OOO,
I just see what you mean.
BUT AFAIK VFP has no error message "Divide by zero" (except for MOD() function). You must have "Field numeric overflow" if you put that value in a table. Why one of the results is greater than zero but other is smaller, hmmm that is question to VFPT.
But if you ask me that is something like NULL it is not greater, not smaller not even equal to zero. It is just "Don't know" :o)
In my old CLIPPER days CA even suppress that error and I have 0 as result.
