"I will now clamp this value between this limits" has the implied contract that
you get the same type as that of the initial value.

Using min and max in the implementation of clamp is specious; in min and max
there is no "preferred" type so they use a fair method of choosing the type of
the result. In contrast, clamp is about a value that occasionally is forced to
a limit.
