title: Is there a name for a byte/word that doesn't wrap around?
body: <p>Certain Processors have registers that are able to do arithmetic on words/bytes without the value wrapping around (i.e. in the case of a byte, the byte is clamped between 0 and 255). I'm not certain but I believe this is used in certain vector extensions designed for image processing (where a clamped byte would be beneficial in terms of representing RGB/RGBA values);</p>
  
  <p>Is there a proper name for arithmetic/registers in which values are clamped and do not wrap or is it/are they just referred to generically as 'non-wrapping arithmetic'/'non-wrapping registers'?</p>
