If you have such a precise requirement (the given tick size), you have to roll your own function, there's no point in a stdlib function, right?
No, I think Chris's is_close_to would probably do the trick, as the relative tolerance would be some fractional multiple of the tick size. In any case, whether or not I would choose to use this function is beside the point. (It's actually a real, though solved problem in my environment, so modifying code to use it wouldn't be worth the effort or potential sources of bugs at this point.) I was only pointing out that there are valid reasons where such a function might be useful to "non-math people," outside the realm of software testing. Knowing when you need something like this is often only discovered after mistakes are made though. Is a numerical analysis course still commonly taught in Computer Science departments? Skip
