I get two big 0s:

  (string-to-number "a")    ; 0
  (string-to-number "<f1>") ; 0

The docstring also says "Parse STRING as
a decimal number and return the number."

... but isn't 0 a decimal number?

But come to think of it, it actually DOES work
for 0!

  (string-to-number "0") ; 0

Its just one can't tell that from the bogus
inputs and their outputs, which are 0 as well.
One can just verify the input, I guess.


Meta: I got this message as a mail, and it
seems it didn't show up in <gmane.emacs.help>.
So I suppose I reply to it as a mail as well,
and that defaults to To: header to the previous
poster, and Cc: header to
<help-gnu-emacs@gnu.org>. Keep it uptime. Atem.
