How do you deal with numbers larger than UInt64 (C#) -

-

in c#, how can 1 store , calculate numbers exceed uint64's max value (18,446,744,073,709,551,615)?

by using biginteger class; there's 1 in the j# libraries (definitely accessible c#), in f# (need test one), , there freestanding implementations such one in pure c#.
