When to use it

0 at Range Min, 1 at Range Max, linear between, and clamped to 0 to 1 at both ends.

The clamp is the whole difference between this and Remap. It is what stops a value from outside the range driving a blend past its endpoints and pushing a colour or a displacement somewhere you never asked for.
