i didn't check yours for accuracy. it is a tricky regex as it must check
for only 1 decimal point and 1 or 2 digit strings around it. i once
wrote one that was a regex with 2 checks against $1 and $2. mine didn't
use lookahead which is why i needed the extra logic.

nope.

$SIG{__WARN__} is too annoying to setup IMO. you might as well use the
POSIX calls to do the same work and get a direct answer.
