</span><span class="pun">&lt;?</span><span class="pln">php

$x </span><span class="pun">=</span><span class="pln"> </span><span class="lit">10.365</span><span class="pun">;</span><span class="pln">
var_dump</span><span class="pun">(</span><span class="pln">$x</span><span class="pun">);</span><span class="pln">

</span><span class="pun">?&gt;</span><span class="pln">

</span>

The above code will produce the following result-

<span class="pln">
</span><span class="kwd">float</span><span class="pun">(</span><span class="lit">10.365</span><span class="pun">)</span><span class="pln">
