Limits on int's in c++

[Khasiar]

Hey,

I am trying to store permutations (huge) in an int and it limits itself so i was hoping there was another way of doing this.

for instance if i want to store a value > 4,294,967,295 in an unsigned int it doesnt work when going past that value

so i moved up to unsigned _int64 which allows 18,446,744,073,709,551,615 but as you may know with permutations you can really have limits if your trying to reach a perfect program.

for those that dont know permutations = pow(n, r) and when your working with things like 13 to the power of 300 = error on all calculators + comps ive tried it on.

so pretty much im trying to store a value in an int that has an unlimited size, any ideas?

Thanks in advance
