There is no *double* FFP format (double won't be fast anymore). The
alternative is to use either IEEE single or double precision FP
format. Has anyone out there any idea how the format looks like?

The other way would be to use really the C function from assembler,
since most assembler produce same object-code as C compilers.

Cheerio,
Peter
