How can I limit the number of digits in an NSNumber?

[Ricardo1980]

Hello!

How can I limit the number of digits in an NSNumber?

I guess I should use NSDecimalNumber and let RestKit transform it to NSNumber, isn't it?

What I want is to limit my number in 9 digits. Of course my server expects a number in the json file, not a string, so not sure how to do it and add it to restkit.

Any idea?

Thanks.
