Parses longitude from the provided string, assuming that the DecimalDegrees (DD) format is in use.

Parameters

str

a string to be parsed

lonInDeg

the parsed longitude in decimal degrees, passed by reference (out)

errorMessage

an error message, passed by reference (out), that contains detailed error / warning information

Return Value

true - the function has succeeded, false - it has failed

Remarks

The function verifies validity of its arguments before running parsing. The function recognizes the DecimalDegrees (DD) format, for example: -77.049. The function verifies the validity of the parsed result also. The valid longitude (in degrees) is a real number in the range from -180.0 (inclusive) to 180.0 (inclusive).

Example

This sample shows how to call the TM.ParseLongitudeInDeg method from C# code:

 string errorMessage = String.Empty;
 
 string str = "-77.049";
 double lonInDeg = Double.NaN;

 if (TM.ParseLongitudeInDeg(str, out lonInDeg, out errorMessage))
 {
     Console.WriteLine("LonInDeg: " + lonInDeg.ToString());
 }
 else
 {
     Console.WriteLine(errorMessage);
 }
