The line number where the error occurred if JSON source was not successfully parsed.

<member name="result" type="Variant" setter="set_result" getter="get_result">
A [Variant] containing the parsed JSON. Use typeof() to check if it is what you expect. For example, if JSON source starts with curly braces ([code]{}[/code]) a [Dictionary] will be returned, if JSON source starts with braces ([code][][/code]) an [Array] will be returned.
[i]Be aware that the JSON specification does not define integer or float types, but only a number type. Therefore, parsing a JSON text will convert all numerical values to float types.[/i]
