An Ordinal-Input Function is a Value-Input Function whose Function Range is an Ordinal Set (with Ordinal Data Values).

• AKA: Ordinal-Valued Function, Ordinal Function.
• Context:
• Example(s):
  • [math]\displaystyle{ f }[/math](Large) ⇒ 1.4
  • [math]\displaystyle{ f }[/math](Large) ⇒ True, is an Ordinal-Input Relation.
  • …
• Counter-Example(s):
  • [math]\displaystyle{ f }[/math](1.1) ⇒ Red.
  • [math]\displaystyle{ f }[/math](1.5) ⇒ 5.1, a Real-Valued Function.
• See: Ordinal-Output Function, Categorical-Input Function, Numerical-Input Function.
