It does indeed "look better", in the sense that the original bug looked like crap. But it still
qualifies as Rakudo getting confused.

0e99999999999 is zero, not NaN. No amount of nines after the 'e' should make it not zero.

That looks better. assigning to moritz++ for testification.

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
vomiting. =-)

Agreed that the actual value is wrong.
