long double is compiler specific, so not supported widely.

If you need higher precision that the default 64 bit in Win64 via SSE2, you can still use the old x87 80 bit FP code and as MMX is now redundant being surpassed by SSE, you don't have to mess around with preserving MMX registers as they don't normally get used.

I gather there are specialised libraries for very large numbers but I don't really know much about them.

did you check the source and the running EXE in the ZIP archive LongC64.zip? If not, please make the effort. You can find it here under the first post.

Sure. We have discussed this at length over the years.

Erol,

You're welcome. I feel a bit rusty, but it works.
