You could always do this, unless you are set on using a regular expression:

if($num>=0 && $num<=1.01){
 echo number_format($num,2);
}

[PHP] Re: Regex help please

[Manuel Vázquez Acosta]

Try this:
$pattern = '#function
(\w+)\(((?:\$\w+(?:,\s*\$\w+)*?)|\s*)\)\s*\{[.\s]*((?:return\s+[^;]*\s*;)|)[
.\s]*#m';

Notice that \w means:
A "word" character is any letter or digit or the underscore character, that
is, any character which can be part of a Perl "word".

Though, any regexp for this task can be easily fooled; i.e: there's no
regexp for all cases; PHP's language cannot be described properly using just
a regular expression.
