        The actual code for the range checking logic is optimized for the combined
        properties of the source and target types. For example, a non-subranged conversion
        (i.e: <code class="computeroutput"><span class="keyword">int</span></code>-&gt;<code class="computeroutput"><span class="keyword">float</span></code>), requires no range checking, so <code class="computeroutput"
