# Difference between NSInteger and NSUInteger

Can any one tell me the [difference](https://www.mindstick.com/articles/157114/good-news-or-bad-news-and-the-difference-is) between NSInteger and NSUInteger in Objective-C?

Which is better to use in an [application](https://www.mindstick.com/articles/12824/calculator-application-in-android) and why it is better?

You always be aware of integer conversion rules dealing with NSInteger and NSUInteger.\
For example: NSInteger can takes and returns negative values, and NSUInteger takes values and returns only unsigned values.

```
NSInteger nsinteger = -1;NSUInteger nsuinteger = 1;NSLog(@"%d",nsinteger<nsuinteger);
```
