String To Number (PMML)
Converts strings in a column (or a set of columns) to numbers.
If the node fails to parse a string, it will generate a missing cell and append
a warning message to the KNIME Console with detailed information.
If the optional PMML inport is connected and contains preprocessing
operations in the TransformationDictionary the conversion operations
of this node are appended.
