That is: floor( 8 / (-3) ) == floor( -2. ) == -3
Or do you want -2?
and ($x mod $y) be ($x - $x div $y).
Hmm, since 8 - (-3) == 11 this definition hardly works.
But even with $q = floor( $x / $y ) and $r = $x

At least, not in cases where the intended result is consistent across 0.
Lots of date arithmetic falls into this category, and works beautifully with
the definitions above.
Does it? If you have a year 0, what is the number corresponding
to the middle of that year? Is it 0.5? Is
Just a nit, for the record, with no great perl relevance:

Sure (of course if there were a year 0 instead of becoming 1 BCE)

Sure

I would really like to see ($x div $y) be (floor($x/$y)) and ($x mod $y) be
($x - $x div $y). If the divisor is positive the modulus should be
positive, no matter what the sign of the dividend. Avoids lots of special
case code across 0 boundaries.
