[[Category:Computer Architecture]]
A ''signed'' value is a binary value stored in two's compliment representation, where the most significant bit is used as a negative sign.
Example: A single unsigned [[Word#Byte|byte]] (8 bits) stores an integer value in the range of 0 to (2^8 - 1 =) 255. If the byte is treated as a signed value, then values from 0-127 (0x00-0x7F) are treated as the positive integers 0-127, and the values 128-255 (0x80-0xFF) are treated as negative integers -128 to -1.
