Remove extra zeros when converting a double to a string in Objective C

Question

So when I convert a double to a string using something like this:

double number = 1.1;
text = [[NSString alloc] initWithFormat:@"%f", number];

The variable text ends up printing something like this: 1.100000. I realize that this is because of the way the computer stores the value however I need an easy way to remove those extra zeros and, if need be, the decimal as well if the number turns out to an integer.

Thanks!

Try to look at NSNumber and NSNumberFormatter with it's usesSignificantDigits property. It is probably what you are looking for.
