Question

I have a little problem. Essentially, the code:

uint64_t myInteger = 98930 * 98930;
NSLog(@"%qu", myInteger);

…just gets it wrong. I get ‘1197210308’ as the output, which is evidently incorrect. Why is this happening? It can’t be that a uint64_t is too small, as they apparently go up to 18 and a half quintillion. Anyone have any idea?

Answer 1

Try casting the first number so the operation is made using that type:

uint64_t myInteger = (uint64_t)98930 *98930;
