Sounds interesting. Out of curiosity, just how are you defining your
128-bit integer types?
__int128
There is no unsigned as yet. Many other things must be done first:
o printing them with printf. Format "%I128d"
o scanning them with scanf. Same format
o Algebraic simplifications in the compiler
C99 introduced the concept of "extended
integer types" (C99 6.2.5); are you using that? If not, I encourage
you to do so. And are you making intmax_t and uintmax_t 128 bits?
Very probably but that is too son. I have to get the basics right first.
In 32 bits I use operator overloading and there is no printf support...
This is different.
