Interesting question!
I would assume str() and int() to use a similar algorithm, but I never
looked at their actual implementation, so this is just speculation.
Also, as a general rule I thought one shouldn't rely on implementation
details since they could change (admittedly, quite unlikely for something as
basic as this though).

Fair enough.
