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.
