Behavior of random integer generation: Python randint [a,b] MATLAB randi [a,b] Mma RandomInteger [a,b] haskell randomR [a,b] GAUSS rndi [a,b] Maple rand [a,b]
In short, NumPy's `randint` is non-standard (and, I would add, non-intuitive). Presumably was due due to relying on a float draw from [0,1) along with the use of floor. The divergence in behavior between the (later) Python function of the same name is particularly unfortunate. So I suggest further work on this function is not called for, and use of `random_integers` should be encouraged. Probably NumPy's `randint` should be deprecated. If there is any playing with the interface, I think Mma provides a pretty good model. If I were designing the interface, I would always require a tuple argument (for the inclusive range), with possible `None` values to imply datatype extreme values. Proposed name (after `randint` deprecation): `randints`.
