... byte as the sign bit . Once again , a 0 in the sign bit will mean that the value stored is nonnegative , and a 1 will mean that the value is negative . Next , we divide the remaining seven bits of the byte into two groups , or fields ...
... byte with the mask 00100000 , which produces a byte of all Os if and only if the third bit from the high - order end of the bit map is itself 0. A program can then act accordingly by following the AND operation with a conditional branch ...
... byte bit pattern 0000010100000010 , which con- sists of the byte 00000101 ( represented by 5 ) followed by the byte 00000010 ( represented by 2 ) , and the pattern 17.12.25 would represent the three - byte bit pattern consisting of the ...
