iphone - store NSTimeInterval on a coredata

Question

I have an entry on a core data entity that represents a NSTimeInterval.

First question: How do I represent this entity on the dababase model? Double? Float?

Then, when I store it, is it fine to create an object like

[NSNumber numberWithFloat:myTimeInterval];

or

[NSNumber numberWithDouble:myTimeInterval];

or should I convert everything to string and store it like that?

thanks

Answer 1

NSTimeInterval is a double. Store it with the latter line. There's no need to store it as an NSString.
