As sibling comments have mentioned, "operator" here is being used in the programming language sense of the word, not the mathematical sense. Using the name "mod" [as in mod(a,n)] or "modulo" for the mapping that takes integers to a particular representative of its equivalence class in Z/nZ ("integers modulo n") doesn't seem like an unreasonable choice to me.
