Show HN: An Uncertainty Calculator

Hi, author here, I just want to say that if you happen to know more correct uncertainty propagation for scientific functions, please submit a pull request.<p>Also, this is aimed at undergraduates, so it ignores covariance.

I was sort of hoping it might sometimes result in an answer of &quot;a suffusion of yellow&quot;.

I think it doesn&#x27;t work. It claims:<p>(1+-2) &#x2F; (1+-2) = 1+-2.8<p>When, of course, the result could be any real number.

1&#x2F;(1+-1) = 1+-1<p>Great idea, but as other comments have noted, completely wrong.
