int / float 1

[XoFF]

i want to make the sum of very large numbers. My question is can i use it with a long type? cause now i use a double it works fine but i don't wanna use floats just positive numbers... maybe a long unsigned???

also what is l used for %lf?
ex: scanf("%lf",&getala);

How large are these numbers?
Say 1,000,000,000,000 ?

Integral numbers (int, long etc) are precise, but have a fairly limited range when compared to say a double.

On the other hand, doubles gain a huge amount of range by sacrificing a similarly huge amount of precision - that is, all floats/doubles are approximations.
