distanceFromLocation to string is way off

Question

So I am trying to take distanceFromLocation and show it as "8 miles" or "1.5 miles" but I end up with "93129432 miles". See comments inline for where it goes wrong.

 double roundDouble = round(returnedDouble);
    NSNumber *mylngDoubleNumber = [NSNumber numberWithDouble:roundDouble];

    if(latDouble == 0 || lngDouble == 0 || roundDouble == 0){
        NSString *str = [NSString stringWithFormat:@"0 mi."];
        self.distance.text = str;
    }else {
        NSString *lngDoubleString = [mylngDoubleNumber stringValue]; <-- ok here '98'
        NSString *str = [NSString stringWithFormat:@"%d mi.",lngDoubleString]; <-- bad here '93129432'

        self.distance.text = str; 
    }

So, the computation works correctly, but the string formatting doesn't? — Matt Ball, Mar 08 '11 at 04:14
change the @"%d mi" to @"%@ mi" or @"%d mi.",lngDoubleString to @"%f mi.",[lngDoubleString floatValue]; — Satya, Mar 08 '11 at 05:04

it should be [NSString stringWithFormat:@"%@ mi", lngDoubleString]; because you are formatting a string.
