<br>
Does anyone know why we don&#39;t have a concept std::arithmetic?<br>
<br>
We have type traits std::is_integral and std::is_floating_point and a<br>
composite type trait std::is_arithmetic that is their union. But in<br>
&lt;concepts&gt;, we have std::integral and std::floating_point, but no<br>
std::arithmetic.<br>
<br>
Is there known rationale for this?<br>
<br>
<br>
Regards, Phil.<br>
