in thread Definition of numerically equal and rationale for 'you' == 'me'

I'm coming in a little late, but this is what I got on Mac Lion, perl-5.14.2:

perl -e "print \"true\" if 'nanosecond'== 'nanosecond'"

perl -e "print \"true\" if 'nanosecond'!= 'nanosecond'"
true

perl -e "print \"true\" if 'informal'== 'formal'"

perl -e "print \"true\" if 'informal'!= 'formal'"
true

strange

Update: Oh I see ... 'nan'...'inf'

Could you give me the output of the following, please?

perl -le'print "foo" == 0 ? "as per docs" : "deviates from docs"'

perldata:

strings that aren't numbers count as 0, just as they do in awk

[Anonymous Monk]

You missed the update :)

$ perl -le " print int $_ for qw/ na nan nanners in inf infant /"
0
-1.#IND
-1.#IND
0
1.#INF
1.#INF

perlop mentions NaN, while bigint...

Saw the update later. I get it, thanks :)

[ikegami]

I didn't miss it, I misunderstood it. I thought you meant it was returning NaN for all strings, not just those starting with "nan".

That's rather weird, but it is consistent with "123abc".
