If you really want to make it work well , you should even add some code to ensure that only digits can be entered in the second editbox for length or precision 如果要想使该框架的性能更好一些，您甚至应该添加一些代码，以确保只能在第二个编辑框中输入数字（用于长度或精度） 。
Numerical control ( nc ) is a method of controlling the movements of machine components by directly inserting coded instructions in the form of numerical data ( numbers and letters ) into the system 数控（ nc ）是一种通过直接向系统输入数字数据（数字和字母）形式的编码指令以控制机床部件运动的方法。
Flexible dimming control utilizes either an analog control signal or direct digital pwm control without external rc filtering . this also increases dimming accuracy at low brightness levels 电路采用灵活的调光控制方式,既可输入模拟控制信号,也可直接输入数字脉冲宽度调制信号而不需要外置rc滤波器。
Soundbite : ( english ) " at some point , there is no point in using a calculator , because if you can ' t think anyway , then what ' s the point of using a calculator ? 不过，目前绝大部分大学在入学考试中，都不允许使用这种计算器。他们认为，只有记住基本计算公式，并能熟练使用他们，才能培养学生的逻辑思维能力，而代数计算器让学生们变成输入数字和抄写答案的懒虫。

I have introduced many more swt controls , such as tree for creating tabular trees ; canvas for drawing pictures ; slider , scale , and spinner for entering numeric values ; progressbar for displaying progress ; styledtext for entry of text with attributes ; and popuplist for simple dynamic menus 系列的第三期中，我介绍了更多的swt控件，比如用于创建表树的tree ；用于绘图的canvas ；用于输入数字值的slider 、 scale和spinner ；用于显示进度的progressbar ；用于输入具有某些属性的文本的styledtext ；以及用于简单动态菜单的popuplist 。
Much of software testing concerns itself with " corner cases " and " stupid input . " it is an unfortunate fact of life that a piece of software has to stand up to all sorts of things that the designer didn t foresee - that some joker attempts to enter characters from the cyrillic alphabet where digits were called for , as an example 多数软件测试的重点是“角落的状况”和“愚蠢的输入” 。软件不得不禁受各种设计者没有预见的情况（比如一些开玩笑的人在应该输入数字的地方输入古斯拉夫字母）这是一个非常不幸的事实。
