<moritz> p6​: say (-8) div 3
<p6eval> ..niecza v16-23-gaa61ed5​: OUTPUT«-3␤»
<p6eval> ..rakudo 2a962e​: OUTPUT«-2␤»
<masak> huh!
<masak> I think Rakudo is right here.
<masak> it's truncate-towards-0, not round-down semantics.
* masak submits nieczabug
<sisar> masak​: no. the spec says "In general, div should give the same
result as​: $x div $y == floor($x/$y) "
<masak> oh!
* masak unsubmits the nieczabug and submits rakudobug

From @usev6

This works now​:

$ perl6-m -e 'say (-8) div 3'
-3

I added a test to S03-operators/div.t with the following commit​: Raku/roast@d03302f512

@usev6 - Status changed from 'new' to 'resolved'
