|

will only ever be true for built-in types; if you want to check for a user-defined
|

class type that behaves "as if" it is an integral or floating
|

point type, then use the <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">numeric_limits</span>
