I'm a heavy std::clamp user, but I'm considering replacing it with min+max because of the uncertainty about what will happen when lo > hi. On windows it triggers an assertion, while other platforms just do a min+max in one or the other order. Of course, this should never happen but can be difficult to guarantee when the limits are derived from user inputs.

Sounds to me like you are missing a validation step before calling your logic. When it comes to parsing, trusting user input is a recipe for disaster in the form of buffer overruns and potential exploits.

As they used to say in the Soviet Union: "trust, but verify".

The answer is of course

    clamp(min(a,b), max(a,b))

classic c++
