Just a somewhat minor bug.
The documentation (both in-editor and in the online documentation) for the InRange (float) function have an incorrect description.
The function is described as "Returns V clamped to be between A and B (inclusive) "
That is, in fact, the description of the Clamp (float) function.
The InRange function merely checks if the value is within the specified range, and returns true if it is and false if it is not. It does not return a float value at all.
