  1) The 80386 *can* perform 64-bit (and 128-bit and 1024-bit if you want)
floating point calculations. Not just as fast as the 80387 co-processor.

  2) When I said "80386" I was referring to the architecture and not to
the CPU per se. Arguably the 80387 co-processor is part of the overall
architecture (hence the numbering).

  The 286 architecture also had a 287 co-processor, but I'm not sure if
it supported 64-bit floating point numbers. Maybe.
