Unsigned binary numbers are, by definition, positive numbers and thus do not require an arithmetic sign. An m-bit unsigned number represents all numbers in the range 0 to 2m − 1. For example, the range of 8-bit unsigned binary numbers is from 0 to 25510 in decimal and from 00 to ...

The signed numbers possess a sign bit so that they can distinguish positive and negative integer numbers. The signed binary number method has both the sign bit and the magnitude of the number. In this pattern, a binary number holds a bit for a sign symbol. If this bit is set to 1, th...
To "chop off the extra bits", we need to AND with the bits that we are interested in. For example, if we want to end up with an unsigned byte (8 bits), we need to AND with the value 0xff (255 in decimal)— 11111111 in binary or in other words, "the first 8 bits set". ...

does the binary math and sets the flags appropriately. It's up to you, the programmer, to know which flag to check after the math is done. If your program treats the bits in a word as unsigned numbers, you must watch to see if your arithmetic sets the carry flag on, indicating ...
13.5.1 Negative numbers Signed integers use a notation called 2s complement to represent negative values. In this representation the binary digits have a ‘1’ in the most significant bit column if the number is negative, else it is a ‘0’. To convert a decimal value into 2s complement no...
The eight bit binary value %1100_0000 could represent an IBM/ASCII character, it could represent the unsigned decimal value 192, or it could represent the signed decimal value -64. As the programmer, it is your responsibility to use this data consistently. ...
