Wow. I just finally understood what your RFC was going for. I thought
you were trying to cover the case where ($a%$b)==0, but you're not,
you're trying to do truncated integer division regardless of
remainder. I also missed the fact that div_function does the right
thing already as well. My bad for emailing from the bus.
Okay, that's another animal entirely.
Do we need a new operator for that? It feels un-php to me, and the
kind of problem bigint objects should be meant to solve. On the other
hand, having $a/$b != $a/$b (Off by more than 100 in this instance).
But back on the first hand, that's consistent with other operations on
large floats anyway. PHP_INT_MAX + 1 != One more than PHP_INT_MAX,
for example.
