<dt><em>Description</em>:</dt>
<dd><p><code>SELECTED_INT_KIND(R)</code> return the kind value of the smallest integer
type that can represent all values ranging from <em>-10^R</em> (exclusive)
to <em>10^R</em> (exclusive). If there is no integer kind that accommodates
this range, <code>SELECTED_INT_KIND</code> returns <em>-1</em>.
