Converts the given value to the specified target data type and returns it.

Conversions between data types.

		BOOLEAN	INTEGER (accepts all Numbers	FLOAT (accepts all Numbers	STRING	DATE	URI	USERDEFINED
BOOLEAN	->	as is	false -> 0L true -> 1L	false -> 0d true -> 1d	false -> "false" true -> "true"	-	-	-

FLOAT	->	0 -> false; true otherwise (accepts all Numbers)	discards fractional digits while casting to Long (accepts all Numbers)	as is (accepts all Numbers; will be cast to Double)	computerized scientific notation	taken as milliseconds since 1970-01-01, 00:00:00 GMT; discards fractional digits	-	-
STRING	->	"true" (ignoring case) -> true, false otherwise (Boolean.parseBoolean(String))	parsed as signed decimal representation (Long.parseLong(String))	parsed as computerized scientific notation (Double.parseDouble(String))	as is	parsed as ISO 8601	parsed as URI (URI.create(String))	encoded as UTF-8
DATE	->	-	milliseconds since 1970-01-01, 00:00:00 GMT as Long	milliseconds since 1970-01-01, 00:00:00 GMT as Double	formatted as ISO 8601	as is	-	-

Parameters:

value - the value to be converted; this should typically be a direct equivalent to an ADEPT2 data type

targetDataType - the target data type to which the value should be converted

Returns:

the converted value

Throws:

ConversionException - if the conversion is not possible
