00:29 <[Coke]> rakudo: say 0e99999999999
00:29 <p6eval> rakudo 67778a: OUTPUT«NaN␤»

NaN?

Perl 5 thinks:

$ perl -le 'print 0e99999999999'
0
$ perl -le 'print 1e99999999999'
inf

and I find its answers more pleasing.

Whoops, I meant better in that it actually returned a value instead of

Agreed that the actual value is wrong.
