OK, there are two problems mentioned in the report. The second one (with 0.A being created) is part of RT#126016 which is now resolved. ✓
As for the other issue, the behavior has changed a little bit: my $a = 0.89999999999999999999; my $b = $a.perl.EVAL; say $a.WHICH; say $b.WHICH ¦c8ec2999bee^: «Rat|89999999999999999999/100000000000000000000Rat|9/10» ¦c8ec299,HEAD(5929887): «Rat|89999999999999999999/100000000000000000000Rat|89999999999999999999/100000000000000000000» The commit in question is (2015-09-25) https://github.com/rakudo/rakudo/commit/c8ec2999bee8b2396419d9ebf54e5e2656a6c0b8 As already mentioned, the problem is a little bit different. Rats with too big denoms are weird, and there's a ticket for that: RT#132313 I'll interlink the tickets and leave this open. On 2015-09-19 00:28:52, labster wrote: > You've reported the wrong bug.
