its more like
5.43 without 2.1
which in APL is
(x = y)/y with some tolerance for what is considered equal
6 5 4 3 -. 4 3
6 5
I am not sure I like this but will have to get used to it.
From dictionary:
x-.y includes all items of x except for those that are cells of y .
-.y is 1-y ; for a boolean argument it is the complement (not); for a
probability, it is the complementary probability.
Can this also work as APL tilde ~ ?

Donna;
In APL:
1.1-.1
1
that is, subtraction is performed.
In J:
1.1-.1
1.1
that is the "less" verb is performed. For one who has APL as his
first c.l., this is a gotcha. The need to prefix fractional nouns
with 0 does not come naturally.
This observation _was_ tangential to the discussion.
It is not my nature to be a (canine)pack animal. Perhaps it's the
meme you are posting that is attracting the swarmed response.
Perhaps we're being too Shroeder'esque and overcomplicating things.

I am not sure what you refer to as a gotcha.
Unless it refers to having fun sending me e-mails in which there
is endless need to re-explain the same points as in the
childhood game of repeating back the last thing that was said
by the other person in hopes of frustrating and exhausting them
but in this version with slight variation and working in packs.

If your question was something else, I apologize for my lack
of proper attention.
I'm thinking this is different in the case of 1 and 1.1-.1, where
1 = 1.1 - .1
but
([]dr 1){ne}[]dr 1.1-.1
NB. Excuse the APL, I'm being lazy in not looking up the
foreign for data representation.
(J-note)
1.1-.1
1.1
was something I had to think about for a bit. Definitely a gotcha.
