Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In computing, signedness is a property of variables representing numbers in computer programs. A numeric variable is signed if it can represent both positive and negative numbers, and unsigned if it can only represent positive numbers. While signed numbers can represent negative numbers they lose a range of larger numbers which can only be represented with unsigned numbers of the same size (in bits). This is because in signed variables, roughly half the possible values are negative values. Unsigned variables can dedicate all the possible values to the positive number range. For example, a signed 16 bit integer could hold (Approximately) the values -32768 to 32767, while an unsigned 16 bit integer could hold the values 0 to 65535.
