I would like to show my position on the map, I'm using CLLocation for doing it

Here is my code:

CLLocationCoordinate2D coordinate;
coordinate.latitude = latitude;
coordinate.longitude = longitude;

With latitude and longitude is float type and get from database But when i convert to float value so i get wrong value:

float latitude = [myLatString floatValue];

and result:

myLatString : 10.861714

float value : 10.8617144

So i can't load to my mapview with above values.

I searched on google, someone said use NSDecimalNumber but how to work NSDecimalNumber with CLLocation??

Please help me

    What were you expecting to get? And why are you storing numbers as strings in your database instead of just numbers? – Abizern Dec 26 '14 at 11:14

Use of NSDecimalNumber to convert NSString to float.

NSString *myLatString = @"10.8617144";
NSDecimalNumber *decimalPoint = [[NSDecimalNumber alloc] initWithString: myLatString];
float latitude = decimalPoint.floatValue;

  • Really, just a down vote. To the down voter have you read what OP required here. And give a comment if you think that this is wrong answer. – Kampai Dec 26 '14 at 11:47

Use doubles. Latitude and longitude are CLLocationDegree, which are double.

Also best to use CLLocationCoordinate2DMake:

CLLocationCoordinate2D loc = CLLocationCoordinate2DMake([myLatString doubleValue], [myLngString doubleValue]);
