Fixed point operations

WebConversely, if a register has a wrapping mode of operation, an overflow condition is set to the appropriate value within the range of the representation. Saturation and Wrapping. Consider an 8-bit unsigned word with binary-point-only scaling of 2-5. Suppose this data type must represent a sine wave that ranges from -4 to 4. WebJan 12, 2024 · In fact, there is only a single sub operation within a single operation were the structure of a fixed point number has to be known: picking the valid digits after a fixed point multiplication. But one thing fixed point does give you is the opportunity to cheat, to take shortcuts, to use less than full 16.16 precision.
