Hi,
Yes, sorry, this isn't my actual code, I wrote it in the mail quickly, I
know I forgot the semis etc. What I am trying to do is find out if a 'bit'
in a double is ON or OFF and return the value. So I am using the int to
shift through the double and return the value, but I am getting errors. I
don't want to use a long because I need 64 bits!
