> number of elements to process is exactly the difference between last and first index of the range And in Julia, it’s length(a:b) which also works with non-unit step sizes like length(a:x:b) The intent of these expressions seems clearer than the intent of `b-a` and `ceiling((b-a)/x)` with your proposed approach in a zero-indexed language.
