How do computers hold integers over 255
WebIn computer architecture, 256-bit integers, memory addresses, or other data units are those that are 256 bits (32 octets) wide. Also, 256-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size. WebTo negate a signed 8-bit value (ranging from -128 to +127), toggle all the bits, then add 1. A error has occurred if a carry is generated — the initial value was out of range (a negated -128 can’t produce +128). Negating a 16-bit value is similar. Flip the bits of both bytes. Add 1 to the LSB. If a carry is generated, add 1 to the MSB.
