Div rounding

# Every division says how it rounds (owner, 2026-10-02): `floor` down, `ceil` up, `trunc` toward
# zero, `near` to the nearest (a tie to even). `mod.X` is what `div.X` leaves over:
# a equal_to (a div.X b) times b plus (a mod.X b). On numbers with a fraction, `div.near` is ordinary division
# and `floor`/`ceil`/`trunc` give a whole quotient.
