Hi, is there a data type larger than unsigned long long int except double? I don't want double or float because I need to keep it as precise as possible. I also need it to be able to do modulus. How would I do this?

GMP is uniquely great. Yet, how large is very large integer?

tesuji how large you want your number to be???
However large it is it is always generated by computer try multiplying two largest numbers known to u and I think you will end up with getting a longer number!!!!!!
(you can use FFT algorithm to multiply extremely large numbers)

so tesuji can you suggest an algorithm better than FFT for getting large numbers(of the order of 10 power 30 or more)?????????

If I were God first I would create new universe to be able to store quintillion figures of those numbers because Milky Way obviously too small. Then I would install just one quintillion hyper light-speed computers everywhere in that new universe to do multiplication recursively by massive parallel computing. Maybe that will help.

in general Karatsuba is suitable for smaller numbers, Toom-3 for larger numbers and FFT for very large numbers. which is the most appropriate for a particular number depends on the processor.
for example, for a x86/pentium4/sse2 processor, GMP has determined the following thresholds for multiplication (in number of limbs: 32-bits per limb on this processor)
Karatsuba 18 limbs
Toom-3 139 limbs
FFT MODF 456 limbs
FFT 5888 limbs

Hi, I'm trying to make a program that sets up the hight dpi compatibility mode programatically on Windows 10, so that I don't have to set up manually the properties ...
