Detailed Description

The operator changes the logical type of an attribute. The following conversions are allowed: Notice that the conversion from nominal or string to a numeric type ends with a success only if the input attribute values are effectively numbers. This operator works only on data schemata: neither the physical records, nor the preprocessing section are affected.
