Description:
------------
Would simply like to input a hex value and get the float of it back.  The settype of course does not work, or any kind of casting.  A function that parses the binary string introduces a huge amount of overhead when I do 1024 of these values in a row.  I would think that any programming language would have this basic capability.  I'm getting raw data, and a data type that it needs to be converted to.

I checked and didn't see this requested, though I'm sure it has been.

$num = 0x3F800000;
   printf("%f",$num);

I would expect a return value of:
1.00000

What I am getting is the integer value:
1065353216.000000

>What I am getting is the integer value

And the reason is:

#php -r 'echo 0x3f800000;'
1065353216

That does not change my request for a feature.  There is no way of converting to type float or double from a raw form.  This is what I'm asking for.

0x3F800000 should be able to be converted to 1.000000

This is a feature request, as indicated in the Category.
