It is surprising to me that eps(Complex{Float32}) is unsupported currently, given that there are many applications involving complex data where one would like to specify the precision of some operation appropriately. A single line addition to Base will address this: eps(::Type{Complex{T}}) where T…

Yeah. This is kind of weird. On the balance, it sounds like we should support this. Want to make a PR?

edit: so much for it being just one added line :slight_smile:

Yeah, this is exactly what brought it up, but I never got back to it. I don’t know when I’ll have the time to revive the PR either, so assume it’s open and take a stab at it if you want. It’s probably only like an hour or two away: just move some tests, make a small change, and make it a branch off …
