WebUnder a scale factor where the binary point has been moved left two places, you need a modified rule: flip all the bits and add 1/4, or 0.01. All that the fixed point convention has done is move the binary point. If we multiply 111000.11 by 4 (and truncate to stay within 8 bits), we get 100011.00. And that is -29. houzz fountains
