Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
I just learned how to write a calculator. But sometime the answer is not completely right. For example, 80 + 2.53 the answer should be 82.53. But the calculator display the answer = 82.529987.......... And if the number is to large like 9999999999999999999 * 99999999999999999999999999999. The program will get an error.
Can anyone teach me that how to fix this problem, please
I am honestly not too familiar with obj C - however I am a bit of an old school C dev. It sounds like a typing issue, what data types are you declaring your variables as? Shoot us some code.

Data types have limits! Study up and know them :)
