[Qgis-user] Processing: why tools.vector.values is meant to work only for numeric fields?

[G. Allegri]

I've ntoiced that the utility method "values(layer,*fields)" returns only
numeric values, while in case a string is found it returns None. It happens
because a float cast is used [1]
Is it a requriements for other parts of the Processing pframework? In case
it should be documented, because the docs [2] don't tell about this
restriction.
