J.3.5 Integers
- Any extended integer types that exist in the implementation (6.2.5). 
- Whether signed integer types are represented using sign and magnitude, two’s complement, or ones’ complement, and whether the extraordinary value is a trap representation or an ordinary value (6.2.6.2). 
- The rank of any extended integer type relative to another extended integer type with the same precision (6.3.1.1). 
- 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). 
- The results of some bitwise operations on signed integers (6.5).
