Floatval()
http://php.net/manual/en/function.floatval.php
Returns the float value of a string. No need for number format or ifs.
Floatval will also handle negative numbers such as "-.96".

$s = ".96";
Echo floatval($s);

The function you want is number_format

echo number_format(0.96, 2);

Alternatively you can just check for and prepend it if it is missing.

if ($num[0] == '.')
  $num = '0' . $num;

This wont handle negative numbers though, you would need to write a little more logic for that.
