formula and result, taken from the engine's own test suite — every result below is asserted in CI, not written by hand.
fx
=MAKEARRAY(3, 3, LAMBDA(r, c, r * c)) 1 errors
error values observed from the engine — each with a call that produces it.
| error | produced by |
|---|---|
| #ERROR! | =MAKEARRAY(3, 3) |
| #VALUE! | =MAKEARRAY(3, 0, LAMBDA(x, y, y)) |
