Convert decimal coordinate into degrees, minutes, seconds, direction

Question

I have the following so far, but can\'t figure out a tidy way to get the direction letters in without a bunch of messy if statements. Any ideas? Ideally I\'d like to extend

Here's a solution in C#:

    void Run(double latitude, double longitude)
    {
        int latSeconds = (int)Math.Round(latitude * 3600);
        int latDegrees = latSeconds / 3600;
        latSeconds = Math.Abs(latSeconds % 3600);
        int latMinutes = latSeconds / 60;
        latSeconds %= 60;

        int longSeconds = (int)Math.Round(longitude * 3600);
        int longDegrees = longSeconds / 3600;
        longSeconds = Math.Abs(longSeconds % 3600);
        int longMinutes = longSeconds / 60;
        longSeconds %= 60;

        Console.WriteLine("{0}° {1}' {2}\" {3}, {4}° {5}' {6}\" {7}",
            Math.Abs(latDegrees),
            latMinutes,
            latSeconds,
            latDegrees >= 0 ? "N" : "S",
            Math.Abs(longDegrees),
            longMinutes,
            longSeconds,
            latDegrees >= 0 ? "E" : "W");
    }

This is an example run:

new Program().Run(-15.14131211, 56.345678);
new Program().Run(15.14131211, -56.345678);
new Program().Run(15.14131211, 56.345678);

Which prints:

15° 8' 29" S, 56° 20' 44" W
15° 8' 29" N, 56° 20' 44" E
15° 8' 29" N, 56° 20' 44" E

Hope this helps, and that it does the right thing. Good luck!
