C.1.5 Integers (J.3.5)

• Any extended integer types that exist in the implementation (6.2.5).

  None

• 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 (6.2.6.2).

  Signed integer types are represented as two’s complement. Extraordinary value is an ordinary value.

• The rank of any extended integer type relative to another extended integer type with the same precision (6.3.1.1).

  Not applicable to this implementation.

• The result of, or the signal raised by, converting an integer to a signed integer type when the value cannot be represented in an object of that type (6.3.1.3).

  When an integer is converted to a shorter signed integer, the low order bits are copied from the longer integer to the shorter signed integer. The result may be negative.

  When an unsigned integer is converted to a signed integer of equal size, the low order bits are copied from the unsigned integer to the signed integer. The result may be negative.

• The results of some bit-wise operations on signed integers (6.5).

  The result of a bit-wise operation applied to a signed type is the bit-wise operation of the operands, including the sign bit. Thus, each bit in the result is set if--and only if--each of the corresponding bits in both of the operands is set.
