Do NSDouble, NSFloat, or other types than NSInteger exist?

Question

Over at In Cocoa do you prefer NSInteger or just regular int, and why?, there was mention of NSDouble and NSFloat, but I can\'t see a reference for

Answer 1

There is no NSFloat but I know the Core Graphics API eventually changed from float to CGFloat so that it could use a double on some architectures.

It is best to use the exact types that API headers declare. This makes type changes automatic if you ever recompile your code for a different target.
