To add a precision to others' answers : float refs are unboxed _locally_. If you rewrite your code as let r = ref 0.0 in for i = 0 to 1000_000_000 do r := float i done; Printf.printf "%f\n" !r; Printf.printf "words: %f\n" (Gc.stat ()).Gc.minor_words then it runs at about the same speed as you other version.
