Fixed point negative numbers
WebFixed-point computation is precisely the place where using a properly engineered class will save you from lots of bugs. Therefore, you should write a FixedPoint8 class. Test and debug it thoroughly. If you have to convince yourself of its performance as compared to using plain integers, measure it. WebNegation using sign/magnitude representation consists of flipping the sign bit from 0 (positive) to 1 (negative), or from 1 to 0. One's complement. Two's complement –– …
