[Python-Dev] Symmetry arguments for API expansion (original) (raw)

I know this is all done, but for completeness’ sake:

I just noticed math.trunc() and trunc().

So wouldn’t the “correct” way to check for an integral value be something like:

obj.trunc() == obj

I don’t think this has any bearing on adding is_integer() methods to numeric objects, but might if we wanted to add a generic is_integer() function somewhere.

In any case, I don’t recall it being mentioned in the conversation, so thought I’d complete the record.

Thank you! As you may or may not have noticed in a different thread, we're going through a small existential crisis regarding the usefulness of isinteger() -- Serhiy believes it is not useful (and even an attractive nuisance) and should be deprecated. OTOH the existence of decmpdisinteger() seems to validate to me that it actually exposes useful functionality (and every Python feature can be abused, so that alone should not ) -------------- next part -------------- An HTML attachment was scrubbed...
