my reason is that I often use
but then decide I want to us abs and need
instead of arr.abs().max() (and often I write that first to see the
I don't like
because I have to concentrate to much on the braces, especially if arr
is a calculation
I wrote several times
silly, but I use it often and np.is_close is not useful (doesn't show how close)
Just a small annoyance, but I think it's the method that I miss most often.
