(let ((quotient remainder (floor x y)))
(+ (* quotient z)
(* remainder (floor z y))))
Where floor is a function which returns multiple values rather than a list or vector of results?
Also, but this is entirely on me being an absolute dullard, I like having the brackets around each binding as a kind of guardrails for my mind to not lose track of where I am and what belongs where.
(let [[quotient remainder] (floor x y)]
(+ (* quotient z)
(* remainder (first (floor z y)))))
Because in Clojure there's no multiple value bind, when you want to return many results from a function, you wrap it in a vector, and that means you than just destructure that vector. That also means, it's not smart enough to know if it's used in a single value context or multi value context, so you need to always get the value out of the vector, which is why I call first in that second call to floor.
