Use `==` instead:

user=> (== 42 42.0)
true
user=> (== 42 42M)
true

    Newbie question :

    user=> (= 42 42)
    true
    user=> (= 42 42.0)
    false

    I did not expect last result.

    I understand that underlying classes are not the same
    i.e
    user=> (class 42)
    java.lang.Long
    user=> (class 42.0)
    java.lang.Double


    but anyway I'am surprised

    Cheers
