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.*/#if TARGET_CPU_68K
