ISO Standard: “Any extended integer types that exist in the implementation (C99 6.2.5).”
Implementation: There are no extended integer types.
ISO Standard: “Whether signed integer types are represented using sign and magnitude, two’s complement, or one’s complement and whether the extraordinary value is a trap representation or an ordinary value (C99 6.2.6.2).”
Implementation: All integer types are represented as two’s complement, and all bit patterns are ordinary values.
