Detailed Description
The operator changes the logical type of an attribute. The following conversions are allowed:
-
from numeric attributes to nominal or string attributes;
-
from nominal attributes to numeric or string attributes;
-
from string attributes to numeric or nominal attributes.
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.
