Differences between IdentifyTask and QueryTask

Why does the identify task return all the data as strings and the query task return all data in it's native format? This is confusing!!

I have to have multiple functions to process my results because sometimes it is a number and sometimes it is a string. Am I missing something or is this how it was designed?

Just to make things more confusing - the query task does something funky to my numeric fields turning 0.999952 into 0.99995215999999998.

Below are some example results:
