So what you want to do is :

::So regardless i want my microcontroller read 0V or FLOAT as 0.::

In other words you have to read ONLY a high and all else is one and same. You do NOT have a requirement to differentiate between a ZERO and FLOAT - so why get into a loop to read a float ?

Your above statement translates exactly into
this. And I AM sober as of now...
