The funny thing is that NSNumber converts to string automatically if it becomes a part of a string  I don t think it is documented  Try these   NSLog   My integer NSNumber      NSNumber numberWithInt 184    NSLog   My float NSNumber      NSNumber numberWithFloat 12 23f    NSLog   My bool YES  NSNumber      NSNumber numberWithBool YES    NSLog   My bool NO  NSNumber      NSNumber numberWithBool NO     NSString  myStringWithNumbers    NSString stringWithFormat   Int     Float    Bool      NSNumber numberWithInt 132   NSNumber numberWithFloat -4 823f   NSNumber numberWithBool YES    NSLog       myStringWithNumbers     It will print   My integer NSNumber 184 My float NSNumber 12 23 My bool YES  NSNumber 1 My bool NO  NSNumber 0 Int 132  Float -4 823 Bool 1   Works on both Mac and iOS  This one does not work   NSString  myNSNumber2    NSNumber numberWithFloat -34512 23f
