Subject: [Caml-list] Bitwise negation operator?
Date: Fri, 21 Feb 2003 17:12:32 -0600 (CST) [thread overview]
Message-ID: <Pine.LNX.4.33.0302211708080.2037-100000@eagle.ancor.com> (raw)
Is there a bitwise negation operator I'm just missing? I'm looking for
the equivelent of C's ~ operator. In Ocaml, it would have type int->int.
In two's complement, I can implement this as either
let lneg x = (-x) - 1
or:
let lneg x = x lxor -1
I dislike depending upon being two's complement for bitwise negation.
Brian
