Hi folks,
I just started learning Elm and tried to make a plot for the bell curve: y = exp(-x^2).
Since in all languages I am aware of (Haskell, Python, Ruby, Julia), exponentiation operator has a higher precedence than an unary minus, I expected curvy_thing x = e^(-x^2)
to work, but it took me half an hour to find out that in Elm unary minus has a higher precedence and I should’ve written e^(-(x^2))
. This behavior is extremely confusing, and I believe it would be great to put a huge red warning in the documentation so nobody can make this mistake again. Also, maybe this behavior can be changed because it is unlikely that someone will need to write (-x)^y
.
