Is there a "Modulus Equals" operator?

Question

position = 14
position = position - position%3
=> 12

That code above works, but I am loath to reference position three times. Is there an equivalent ++ for what I am attempting to do above? I envision something like position =-%3.

I can't find anything in the ruby-docs. Anyone?

position -= position%3, okay down to two. – Theta Jul 20 '13 at 02:43 — Theta, Jul 20 '13 at 02:43
Why do you want to narrow this down so much? – squiguy Jul 20 '13 at 02:47 — squiguy, Jul 20 '13 at 02:47
yeah, and great code readability! – Mike Szyndel Jul 20 '13 at 06:58 — Mike Szyndel, Jul 20 '13 at 06:58

Alternatively (just for some variety):

position = (position / 3) * 3

This assumes position holds an integer, not a float (like 14.0). In which case you could do (position.to_i / 3) * 3.
