value by ranges

displayValue() is the function you need. 
docs.appian.com/.../fnc_conversion_displayvalue.html

To my best understanding displayValue is checks for equality not for less or equal 

can you use match function for this?

I was wondering this too, though the issue might be on setting it up to handle arbitrarily-long input lists, instead of fixed-length lists.  That's why it might end up needing to rely on looping functions and/or functions that loop inherently like where(), as Stefan suggested below.
