Your question isn't understandable until you explain briefly what your problem is,what do you want to do and what is your code to do that?

Before you started that project, you actually ought to learn some basics on geography! Learn that a degree has 60 minutes, and a minute has 60 seconds. And learn the different methods for showing direction (North, East, South, West). And maybe some projections...
Now you write code which might work but you do not understand it.

I don't know hat your ddmm.mmmm format is, especially , but check this:

C#

string ConvertDoubleToSpecial(double coord)
	{
		int deg = (int)coord;
		double min = (coord - (int)coord)*60.0;
		return String.Format("{0}*{1:00.00000}'", deg, Math.Abs(min));
	}

Why the downvote? It is doing exactly what the OP requested for.

Its failing for negative coordinates like -180.xxxx its output is -180-5.xxxxxx
Please Check since i am new to lat long.

Zoltán Zörgő 9-Jan-13 1:47am

Well, can't you change as little as this one? See update...

Singh Vijay Kumar 10-Jan-13 0:58am

I could have done but i thought - sign may have impact on other values.
Well Thanks for support.
