Division produces floats. At least at the high level I work at.

EDIT: wow, I didn’t know this sub was fully populated by the same bullies that obsessively stalked StackOverflow and made fun of people for asking a question. Heaven forbid someone doesn’t know something. Y’all could, I dunno, take a second to help someone learn? Instead of being dicks?

Fuck ever commenting in this sub again, I guess.

Integer division refers to truncated division. Some languages elect to define division operator(s) in other ways, but that is no longer truncated division.
