note 102789 added to language.types.float

I found that 00000000 hex was converting to 1.0 decimal. From the Wikipedia article on IEEE-754 floating point:

The true significand includes 23 fraction bits to the right of the binary point and an implicit leading bit (to the left of the binary point) with value 1 unless the exponent is stored with all zeros.

In hex2float32n, replace:

      $intnumber=bindec("1".$binint);

with

   if ($exp <> -127)
      { $intnumber=bindec("1".$binint); };

and then 00000000 works correctly without affecting "normal" numbers.
