FYI, some major programming languages have clamp:

C++: https://en.cppreference.com/w/cpp/algorithm/clamp.html

.NET/C#: https://learn.microsoft.com/en-us/dotnet/api/system.math.cla...

Java: https://docs.oracle.com/en/java/javase/24/docs/api/java.base...

Ruby: https://ruby-doc.org/core-2.4.0/Comparable.html#method-i-cla...

Rust: https://doc.rust-lang.org/stable/std/primitive.f64.html#meth...

Even CSS has clamp. I have to periodically remind myself that Math.clamp is missing from the stdlib, it's much easier to read when you need to use a bunch. Math.min(lower, Math.max(value, upper)) is fine for a one-off, but when you need multiple instances of clamp in the same expression the extra parentheses become troublesome.

		I do find it strange how Python's min and max are builtin and don't require an import, but 'clamp' isn't provided at all. When I look at https://stackoverflow.com/questions/4092528 I feel the lack of an "obvious way to do it", since the simple approach has variant spellings and there are always people trying to be clever about it.
