Yes, it has, but i'm thinking on an algorithm which not calculates the result,but it generates it into a vector or a list. For example you can get a number with more than 1000 digits as result But if I put every digit of the number into a list I could view it and print it on the screen or into a file. So I think it could be a possible solution for this problem because there is no other data types which could memorize such a number. Opinions ?
