</p>
22 <pre>float v[
3] = {
0,
0,
7};
23 float3 vrot =
<span class=
"RenoLink"><a href=

</a></span><3>(
3.14159f)
<span class=
"RenoLink"><a href=
"operator_times_mat_vec_.html">*
</a></span> v;
</pre>
24 <p>Naturally, operator overloads cannot kick in if all elements of an expression are of built-in types. The following is illegal:
</p>
25 <pre>float v[
3] = {
0,
0,
7};
27 <p>The

"vref.html">vref
</a></span></i> and
<i><span class=
"RenoLink"><a href=
"mref.html">mref
</a></span></i> function templates can be used to work around this issue:
</p>
28 <pre>float v[
3] = {
0,
0,
7};
29 <span class=
