Many years ago, ~2009ish, a friend pointed out that Calculator.app was giving the wrong sign when raising a positive number to a negative exponent. It turned out to be a bug in CFNumber affecting virtually every app.
I noticed the other day that you can type "1+1 sq ft in sq in=" and macOS will helpfully autocomplete the answer: 1,694.0031 square inches. Which is completely wrong. 2 square feet is 288 square inches. It took a few minutes to solve the puzzle of what the hell it is doing.
So take caution trusting Apple's math, which naturally is up to 2x better³—for some value of x.

I’m a recovering Catholic. Sometimes I have intrusive religious thoughts. Recently I have been entertaining the idea that the rapture already happened but only QA was without sin.
