I have some code containing "derivations" which are values that update automatically when any of the values it uses are updated. They are derived from these sub-values, but I don't know what to call them.
I could have sworn there was a math term for it, but I can't seem to find it.
As an example of the term, I've tried searching "derivee" and "derivation source," and checked the thesaurus for "derive."
Is there a single word for the values from which another value is derived?
Also, these aren't arguments for a function, but more like a column in a spreadsheet which some other column is dependent on.
