x1 (li; number/quantity) is the weighted quasi-arithmetic mean/generalized f-mean of/on data x2 (completely specified ordered multiset/list) using function x3 (defaults according to the notes; if it is an extended-real number, then it has a particular interpretation according to the Notes) with weights x4 (completely specified ordered multiset/list with same cardinality/length as x2; defaults according to Notes).

On affix form:

jmina
x1 adds/combines x2 to/with x3, with result x4; x1 augments x2 by amount x3.
