When I input a -1 and take the ln function for natural logarithm, it returns "Not a Number". I upgraded to 10.13.1 and now the calculator doesn't seem to work correctly.
Mac mini, macOS High Sierra (10.13.1)
The natural logarithm function ln(x) is defined only for x>0.
So the natural logarithm of a negative number is undefined.
ln(x) is undefined for x ≤ 0

Yes, I had indicated that that sequence works in my 2nd message. The app is messed up for sure. Be nice if someone could fix it!
Yes I know. I was confused by "rigamarole" and "a pain". 😎

calculator cannot take a natural log of a negative number --states Not a Number
