Anyone know why there is no modulo or mod function in Clojure's core? I know there is a rem function, but that's not the same thing. mod and rem behave differently when the first number is negative.
(mod -2 5) -> 3 (rem -2 5) -> -2 modulo n is important for making things stay in the range from 0 to n-1, for example, if you're working with vectors of length n. You need to ensure that negative numbers wrap around to the positive range. rem does not do this. I'm more familiar with Scheme than CL, and I know PLT Scheme provides both modulo and remainder. But according to the Wikipedia (http://en.wikipedia.org/wiki/Modulo_operation), Common Lisp also provides both mod and rem functions. So why not Clojure? Is it a Java defeciency? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
