NSTimeInterval == double; (e.g. 169.12345666663)
How can I round up this double so that there are only 2 digits left after the ‘dot’?
It would be very good if the result is a NSNumber.
If this is for display purposes, take a look at NSNumberFormatter.
If you really want to round the double in your calculations for some reason, you can use the standard C
round()function.
