Question: calculator errors

The calculator app in 10.13.1 continues to have issues ---> it cannot calculate e^x when x is negative. E.g., a -1 into that function results in "Not a number". Hope there is an update that addresses this issue.

Mac mini, macOS High Sierra (10.13.1)

You can just calculate 1/e^x

It always seems odd that the code of the calculator has to change. Seems like it would be a fairly stable code base.

I imagine the underlying library functions have changed. Seems odd that it wouldn't support negative exponents as it is so easy to calculate if you can already calculate a positive exponent.

Yes, it is a rather ridiculous bug. I also submitted a bug report.

Fortunately the quickest and more accessible calculator in macOS seems to work perfectly fine. If you are wondering what that is, well... Spotlight.

Just type


e^(-1) should work too;

or a more complex calculation like


or ...

Yes, I know that 1/e^x will produce the same result, but it's a pain having to remember that when one is doing calculations. Makes it easy to make mistakes and is annoying to say the least. As one person said, it's surprising that it is not more stable --- very odd.
