uh, perl gives exactly the same answer as Numbers > perl -E 'say .1 + .2 - .3' 5.55111512312578e-17 And python actually gives one more digit than Numbers > python -c 'print(repr(.1 +.2 -.3))' 5.551115123125783e-17 So, I'm not sure why you are claiming "there are way too many digits" and that Numbers is doing something wrong.
