Just like integer precision decreases the smaller the numbers get.  Try 3/2
for example ;-)

You should also consider that POV-Ray uses floats/doubles for nearly every
internal calculation, so the use of integers does not make sense for a lot
of things.  Only as counters and array indices they would be really useful,
but within the common ranges (those that don't blow the memory limits) of
for example +-1000000 the precision limit of doubles should be far (enough)
behind the comma even after several calculations with it.
