Greetings,
I need to evaluate a NSString as a float value (represented by
NSNumber object). Here is my code snippet:
----
   NSString *str = @"28/5";
   NSNumber *nm = [NSNumber numberWithFloat:[str floatValue]];
   NSLog(@"number: %@", nm );
----
this results in:
----
number: 28.0

Right. NSNumber won't evaluate the arithmetic expression, it'll only convert a string representation of a number, stopping when it finds something that's not part of a number (in this case, the "/"). You'll need to do the evaluating yourself.
