<li><p>对于用户输入，计算器是非常宽容的。<br />

2018-09-26 08:46:30 +03:00

<tt>/</tt>， <tt>:</tt>， <tt>\\</tt> 都被认为是除法操作符。<br />

2013-02-18 00:51:59 +04:00
|
|
|
|
<tt>*</tt>， <tt>x</tt> 都是有效的乘法操作符。<br />
|
|
|
|
|
|
而且，需要注意的是 <tt>.</tt> 和 <tt>,</tt> 都被认为是浮点数的小数点，这也就意味着您不能够把它们用作千分符。</p></li>

2010-08-02 20:51:09 +04:00
|
|
|
|
<li><p>您可以根据自己的需要对计算器的大小进行调节，然后通过拖拽窗口右下角符号将其放置在桌面上作为 <a href="../gui.html#replicants">Replicant</a> 。但是您必须保证 桌面栏中的 <span class="menu">Show Replicants</span> 处于激活状态。</p></li>
|
2010-07-08 22:03:41 +04:00
|
|
|

<li><p>键盘面板可以通过选色板来添加颜色，例如： <span class="app">Icon-O-Matic</span>。</p></li>
|
|
|
|
|
|
<li><p>您可以使用 <span class="key">↑</span> 和 <span class="key">↓</span> 键来查看计算器的历史计算内容。</p></li>
|
2010-08-02 20:51:09 +04:00
|
|
|
|
<li><p>您可以选择计算器中的内容，然后可以将其拖拽到任何的程序。或者您可以将它拖拽到tracker窗口或者桌面，那么将会在那儿创建一个具有给内容的文本文件。</p>
|
|
|
|
|
|
<p>更有意思的是，您也可以执行相反的操作：<br />
|
|
|
|
|
|
依据上面的方法创建一个描述了您的计算步骤的剪报，然后将它们拖拽到计算器中进行运算。<br />
|
|
|
|
|
|
或者您也可以直接从邮件中拖拽一个计算表达式到计算其中进行运算。</p></li>
