此函数是 <span class="function"><a href="floatval.html" class="function">floatval()</a></span> 的别名。

此别名是函数改名之后的遗留问题。在 PHP
|
|
旧的版本中由于还没有 <span class="function"><a href="floatval.html" class="function">floatval()</a></span>
|
|
函数，所以你可能需要用到这个 <span class="function"><a href="floatval.html" class="function">floatval()</a></span>
|
|
的别名函数。
