[PDF] Understanding C Integer Boundaries (overflows & underflows

Unsigned Integer Boundaries: Unsigned integers are defined in the c specification as being subject to modular arithmetic For an unsigned integer with width of X bits Arithmetic on that unsigned integer is done modulo 2x Arithmetic operations on a 16-bit unsigned integer is performed modulo 216
