Parameters

Return value

  1. The return value type is the common bit_value of the parameters. Each parameter is converted to this type and then:
    • For two parameters it computes the bitwise NOTOR of the two parameters
    • For more than two parameters the call is semantically equivalent to bit_notor(a0, bit_or(xs...))
  2. equivalent to the call on the elements of the tuple.
  3. The operation is performed conditionnaly.
