> Hello all! wave I’ve been collecting a few of the most cursed corner cases of Julia [WATs](https://www.destroyallsoftware.com/talks/wat) that [I know of here](https://miguelraz.github.io/blog/juliawats/) (WIP), but I would appreciate if people could share their own rare specimens as well. Please ping me with your contributions and I’ll post with proper credit. Here’s an example of what I mean by a Julia WAT: julia\> e = 9998.0 9998.0 julia\> 2e 19996.0 julia\> 2e+4 20000.0 julia\> 2e+5 # This should be 20001.0, right? 200000.0 julia\> 2e + 5 # note the spacing 20001.0 …wat. Some of…

From an a to an e is just a few keys on the keyboard. And it isn’t just e:

```julia
julia> f = 2
2

julia> 3f-3
3.00000e-03

julia> 3f - 3
3

```
