Examples
DataType(0) |
Results in TYPE_INTEGER32. |
DataType({1.0, 2}) |
Results in TYPE_FLOATINGPOINT64. |
DataType((1.s, 2.s)) |
Results in TYPE_COMPLEXFLOATINGPOINT32. |
DataType(Signal.y) |
Checks the data type of a signal's Y component. |
Dim s = Signal As Object |
If Signal is a data set with the signal data structure, then the first DataType call results in the TYPE_OBJECTREF value and the second results in TYPE_AGGREGATE. |
