WebShifting right by n bits on a two's complement signed binary number has the effect of dividing it by 2 n, but it always rounds down (towards negative infinity). This is different from the way rounding is usually done in signed integer division (which rounds towards 0). This discrepancy has led to bugs in a number of compilers. [8] WebOct 9, 2014 · The bits in "b" will stay the same, so while "b" is in 2's complement, "a" will be a positive 32-bit number. So, for example, let int8_t c = -127. If you perform an assignment uint8_t d = c, then "d" will be 129. Can I fill a 32-bit number with the 16-bit parameters so …
