What&#x27;s your point? If you define a &quot;plain integer addition&quot; to be &quot;wrapping binary two-complement addition&quot;, then there isn&#x27;t, otherwise, there is.<p>But the C standard doesn&#x27;t say &quot;+ maps to what you could honestly call plain integer addition&quot; anyway, so it&#x27;s kindof pointless? And if you were to define your own language, you obviously could define &quot;+&quot; to have architecture-specific semantics, whithout appealing to any &quot;plain integer addition&quot;.
