uh, perl gives exactly the same answer as Numbers<p>&gt; perl -E &#x27;say .1 + .2 - .3&#x27;<p>5.55111512312578e-17<p>And python actually gives one more digit than Numbers<p>&gt; python -c &#x27;print(repr(.1 +.2 -.3))&#x27;<p>5.551115123125783e-17<p>So, I&#x27;m not sure why you are claiming &quot;there are way too many digits&quot; and that Numbers is doing something wrong.
