I also got this if your concerned about the display of the point in cases of 25.00

        [fmt setPositiveFormat:@"0.##"];
        NSLog(@"%@", [fmt stringFromNumber:[NSNumber numberWithFloat:25.342]]);
        NSLog(@"%@", [fmt stringFromNumber:[NSNumber numberWithFloat:25.3]]);
        NSLog(@"%@", [fmt stringFromNumber:[NSNumber numberWithFloat:25.0]]);
