preg_match and regular expressions

I am try to check something before its entered into the database to make sure it a percent between 1.0% - 100.0%. What would I need to use a regular expression?

Code:

if(!preg_match("", $new['qotm_table_width']))


         {


                 message_die(GENERAL_ERROR, "You must enter a percentage for the table width");


         }

Rather than do that, I would use this. This assumes that only integers will be entered.

Code:

$intQotm = (int) $qotm_table_width;


if (!($intQotm>=1 AND $intQotm<=100)) {

If fractions can get entered, then just use

Code:

$intQotm = (float) $qotm_table_width;


if (!($intQotm>=1 AND $intQotm<=100)) {
