[issue30046] csv: Inconsistency re QUOTE_NONNUMERIC

[Xiang Zhang]

Xiang Zhang added the comment:

boolean is not quoted since in Python it's a subclass of int so True and False are numeric. This is also the case with numeric objects defining __int__ or __float__ but doesn't get a corresponding string representation.

Since QUOTE_NONNUMERIC will converts data to float when reading, I think we may force the converting even when writing so the inconsistency would disappear. Or document this limitation.
