Define next.
You can use POSIX::ceil(),
but then -1.23 becomes -1 and you might want -2 there?
$ echo -1.23 4.1 5 |perl -MPOSIX -nwle'print

Right now I can only do the above by extracting the first digit using splice
, then add one.
Thanks

$number = int($number) + 1;
also does the same thing.

You need the ceil() function from the POSIX module.
