Some things I should have pointed out is that this does not cover all
the different ways of representing numbers...
For instance, if the submitted value was an octal number like "010",
$clean['num'] is 10 rather than 8 as it should.
If "0x10" was submitted, $clean['num'] == NULL rather than 16...
If "1e4" is submitted, $clean['num'] == float(10000)...
