Standard library version of clip function

Question

I have wrote a utility named nostd::clip that clips a provided value x between a floor and a ceiling:

namespace nostd {
    template<class T>
    auto clip(T floor, T x, T ceiling) -> T
    {
        return std::min(ceiling, std::max(floor, x));
    }
}

Is there some function in std that does the same thing, that I could replace this with? Maybe in C++17?

You could just go through the list of utilities in the library? Wouldn't take more than a few minutes? And then you'd find out what else is there, too. Nobody studies any more :( — Lightness Races in Orbit, Apr 26 '19 at 15:54

You want std::clamp. It does what your custom implementation does.

You really should familiarise yourself with what the standard library provides. A reference site like cppreference is great for that.
