I am trying to compare atom values with numbers. For e.g. -
(def a (atom 0))
(print a) gives -- #Atom@2bcca11e: 0
(= a 0) gives -- false
How do I make this work? How do I compare 0 with the atom value? I want to
do the same for a string to?
I cannot use compare-and-set! for my situation.
You must deref (https://clojuredocs.org/clojure.core/deref) reference
values to get the data inside of it.
(= @a 0)
is the same as saying
(= (deref a) 0)
Hope this helps!

To compare the value of the atom, you should deref it first. Using deref,
you’ll get the current value of the atom:
= (deref a)
0
Or using the reader macro:
= @a
0
So:
= (= @a 0)
true
Hope that helps,

deref is used to pull the value out of an atom, ref, or atom (or other
reference type).
(= (deref a) 0) gives -- true
Also there is a shorthand operator:
(= @a 0)
