          Converts the string value to a double.
 

Method Detail

getValue

double getValue(String val,
                ISpatialReference pUnits)
                throws IOException,
                       AutomationException
Converts the string value to a double.

Remarks

GetValue returns a Double value that is a converted distance from the input string. The input string is formatted that combines a distance value and a suffix abbreviation of the distance units. A spatial reference is used to determine the output distance units.

The following list of suffixes can be used:

Metric Units:

Distance Units Abbrev. Meters per Unit Description
Kilometer km 1000 1000 meters exactly
Meter m 1 International meter.
Millimeter mm 0.001 1/1000 meters exactly
