Evaluate possible methods for supporting numerical values.

[dordille]

Currently apostropheFormBuilderPlugin does not support unique treatment of numerical values. There are two methods that could be used to implement this feature.

An additional column "numeric_value" could be added to the schema for aFormFieldSubmission this would likely be the most speed efficient implementation, however it require additional storage and a layer of complexity to the database model.

Alternatively a is_numeric field could be added to the database aFormField with this field queries on numeric FieldSubmissions? could be wrapped in MYSQL number casting function.
