  A 64-bit CPU has 64-bit long integers and 64-bit pointers. That's about it.

  The FPU has basically nothing to do with the CPU. It's practically its
own independent microprocessor. The bitness of the CPU has no effect
whatsoever on the FPU.
  The 'double' type floating point numbers in practically all computers
has always been 64 bits long and this hasn't changed in any way.

  The only advantage you will get from a 64-bit binary is that you will
be able to use scenes which use more than 4 gigabytes of memory. (With
the AMD64 processor there's also a slight speed advantage due to the
features the processor supports and which the compiler can use to
optimize the binary for speed.)

  (Another theoretical advantage of a 64-bit system is that your scene
files can be larger than 4 gigabytes, as well as the result image,
although this is quite improbable in practice (a 4GB raw image would
have a resolution of about 43600x32700).)
