What are you doing with the numbers? Do you really need 64 bits of precision? The double type carries at least 53 bits of precision, so it might be good enough, depending on what you're doing. On today's hardware, doubles are reasonably fast, too.
hmm, sounds interesting, where can i find these?
btw:
the int64_t worked in my Xcode project and i have everthing as strict as possible (even 'pedantic' is on). no errors. thanks!
