Frac2X, Fix2X, X2Fix, and X2Frac translate to and from
the floating point type "extended" (that's what the X is for).
On the original Mac this was 80-bits and the functions could be
accessed via A-Traps. When the 68881 co-processor was added,
it used 96-bit floating point types, so the A-Traps could not
be used. When PowerPC was added, it used 64-bit floating point
types, so yet another prototype was added.
