On the first day of this series, I’ll present three calculators already.第一天就这一系列，我会目前已经3计算器。 One of the first things I ran into while hunting calculators apps in the BerryReview store was this line of Hewlett-Packard pocket calculator emulators by Lygea Calculators.其中的第一件事我参加成，而狩猎计算机应用服务，在berryreview商店是这条路线的惠普公司袖珍计算器模拟器由lygea计算器。 They are supposed to emulate more or less the same look and function of three classic HP models: the 10B , the 10C and the 12C .他们是为了学习更多或更少相同的外观和功能的三个经典惠普型号： 10 B条 ， 10 C和12 C 。 They all have very specific functions that might matter to certain students or professionals, but they still share enough similarities for me to lump them all together in one single group.他们都有非常具体的职能，可能对某些问题的学生或专业人士，但他们仍然分享足够的相似性，我整他们都一起在一个单一集团。

THE 10B “BUSINESS” CALCULATOR 该10 B条“业务”计算器

The 10B (”B” as in “Business”) is the one that looks the least like its physical counterpart.该10 B条 （有“ B ”作为在“业务” ）是一个看起来最不发达国家一样，其物理对应。 Click the picture to see it in full size.点击图片可以看到它在全尺寸。 The real 10B had a vertical layout that had to be adapted to the Blackberry Curve’s horizontal screen.真正的10 B条，有一个垂直布局已能适应黑莓曲线的横向屏幕。 Even on a Blackberry Pearl, the layout has to change a little because the screen is too small to fit all the keys and functions.即使是黑莓珍珠，布局要改变一点，因为屏幕太小，适合所有的钥匙和职能。 So I guess many functions had to be sacrificed and it’s very hard for me to tell which ones because I am not familiar at all with this calculator.所以我猜的许多功能已被牺牲和它的，我很难分辨哪些是因为我不熟悉，在所有与此计算器。 All I can say about it is from the point of view of someone who is just looking for a better calculator.我所能说的大约是从的角度来看，有人谁是只看一个更美好的计算器。

My first impression was excellent.我的第一印象是好的。 Whatever hang-ups I have with the Blackberry calculator do not apply to this HP 10B emulator.无论杭的UPS ，我与黑莓计算器不适用本惠普10 B条模拟器。 This one really looks and feels like a calculator and I think I could actually have fun punching numbers into it.此一真正的外表和让人感觉更像是一个计算器，我想我真的可以得到乐趣冲压号码到它。 I was surprised because it displays the whole operation/expression in the display.我很惊讶，因为它显示整个运作/表达在显示器上。 For example, you key in 22*16+4*2 and this whole expression will be displayed in one single line until you hit Enter/Equals and get the result of the operation.例如，您的关键在22 * 16 4 * 2 ，这整个的表达将显示在一个单一线，直到您回车键/平等的，并得到运算结果。 I found that very pleasant visually.我发觉非常愉快的视觉效果。 I get to see whatever is actually being calculated.我要见什么，其实是被计算出来的。 There is one problem, though: precedence.有一个问题，虽然：优先。 This calculator does not apply any precedence to the operations so 22*16+4*2 equals 712 when you probably expect 360.这计算器并不适用于任何优先的行动，使22 * 16 4 * 2等于712时，你可能预期360 。 If you want precedence (who doesn’t?), you’ll have to enclose the operations in parentheses: (22*16)+(4*2).如果您想要排名（谁不？ ） ，您都必须附上行动在括号： （ 22 * 16 ） + （ 4 * 2 ） 。 Then you’ll get 360.然后您将获得360 。 That kind of put me off.那种把我赶走。 It’s just not the right thing to do in an expression.它的正义不是正确的事，在一个表达式。 Another problem is the equals sign is tucked in the corner of the layout.另一个问题是，等号是藏在角落的布局。 That may not seem a big deal at first, but it does get annoying after a while.可能似乎不是一个很大的处理，在第一，但它确实让恼人的后一段时间。 That corner is too far.那个角落是太远。

This business calculator probably supports a lot of functions I am not famliar with so I didn’t even bother testing them.这项业务的计算器可能支持了很多功能，我不famliar那么我什至没有理会他们的测试。 I can only assume that at least the functions you can see in the keyboard/layout are fully supported.我只能假设说，至少有职能，你可以看到，在键盘/布局的充分支持。 I will discuss the issues in relation to the manual and information later in this article.我将讨论这些问题在有关手册和资料，后来在这方面的文章。 Meanwhile, you can check a summary of its functions同时，您可以检查的总结其职能 here这里 . 。

THE 10C SCIENTIFIC CALCULATOR 该10 C科学计算器

The 10C is a scientific calculator and it looks quite a lot like its physical counterpart.该10 C是一个科学的计算器和看来，不少像其物理对应。 Click the picture to see it in full size.点击图片可以看到它在全尺寸。 But once again, it looks like a few functions have been sacrificed, maybe because there was no room for all of them in the keyboard/layout or maybe because it was too difficult to implement them.但再次，它看起来像数职能已牺牲了，也许因为没有空间，他们都在键盘/布局，或者因为它是太困难，加以实施。

I couldn’t help comparing the 10C with the 10B.我不能帮助比较， 10 C与10 B条。 The 10C looks more “complete” to me, but probably only because I have a stronger identification with scientific calculations than with business calculations.该10 C看起来更“完整”给我，但可能只是因为我有较强的识别与科学计算，比与商业计算。 I actually studied a little engineering in College, when I was a lot younger.其实，我研究了小工程在高校，当我是一个有很多年轻。 In other words, this one supports many more functions I am familiar with instead of the many functions of the 10B that completely mystified me.在其他换言之，这其中有很多支持更多的功能，我所熟悉的不是很多职能的10 B条，完全我大惑不解。 It will depend a lot on what you do, what you need, what you want.这将取决于很多对你这样做，您所需要的，你想要的。 Meanwhile, you can check a summary of its functions同时，您可以检查的总结其职能 here这里 . 。

Another important distinction of the 10C is the support to RPN, which helps a lot with the precedence problem.另一个重要的区别的是10 C的支持，以逆波兰，其中有很大帮助与优先问题。 Who needs parentheses when you have RPN?谁需要括号时，你有逆波兰？ On the other hand, RPN is all you have with the 10C .在另一方面，逆波兰是所有您已经与10 C 。 The algebraic mode is not supported.代数模式是不支持。 This is obviously not a calculator for ordinary citizens to calculate their gas, income tax or keep track of their expense at the supermarket.这显然不是一个计算器，为普通公民来计算他们的气，入息税或跟踪他们的牺牲是在超级市场。 This calculator packs too many functions that only specialized people are likely to be interested in.这计算器包太多的职能，只有专门的人很可能会感兴趣

What pleased me most about the 10C was that I could finally use the Space key for the “equals” command.有什么高兴我最关心的10 C是，我终于可以使用空格键为“平等”命令。 Well, not quite since it’s RPN only so it’s actually the “enter” command.好，不大，因为它的逆波兰只有这样，它的实际上是“进入”命令。 All the same, I like it.所有相同的，我喜欢它。

THE 12C FINANCIAL CALCULATOR 该12 C金融计算器

The original HP 12C enjoys stardom status among all pocket calculators.原惠普12 C享有的明星地位，各袖珍计算器。 It’s still widely used in its physical form, apparently.它的广泛使用，仍然在其实物形式，显然。 The 12C emulator is a financial calculator that also looks quite a lot like its physical counterpart.该12 C模拟器是一个金融计算器，也期待了不少像其物理对应。 Click the picture to see it in full size.点击图片可以看到它在全尺寸。 Just like the 10C, it looks like a few functions have been sacrificed.就像10 C ，它看起来像数的职能已被牺牲。 But the 12C seems to pack even more functions than the 10B.但12 C似乎包，甚至更多的功能，比10 B条。 I tried to check that carefully but it turned out it was confusing to me because I am not at all familiar with all those financial functions and operations.我试图检查仔细，但原来，这是混淆我，因为我不是在所有熟悉所有这些财政的职能和运作。 I decided that I am simply not qualified enough to judge unless I just look at her from the standpoint of a layman in search of a better calculator.我决定，我根本没有资格不够的法官，除非我只是看看她的立场，从一个门外汉在寻找更好的计算器。 There is a summary of the 12C functions有一个总结了12 C的职能 here这里 . 。

The 12C supports both algebraic and RPN modes, so it is prone to please a wider audience.该12 C既支持的代数和逆波兰模式，因此它很容易，请更广泛的观众。 Whichever you choose, it will be there after you close the application and launch it again.无论您选择，这将有后，您关闭应用程式，并再次启动它。 What will not be there, however, is the stack display if you switch from RPN to algebraic.什么将不会有，不过，堆栈显示如果您切换从逆波兰以代数。 Switch back to RPN and the stack will be gone, and enabling it again is a little annoying.切换回逆波兰和堆栈将会消失，并使它再次是有点恼人。 But I guess most users will just pick algebraic or RPN and commit for life.但我估计大多数用户只需选择代数或逆波兰，并承诺终身。

As a layman, I noticed that the 10B and the 12C both support very interesting date calculation functions that could be useful even to me and are not available in the 10C .作为一个门外汉，我看到这10 B条和12 C都支持很有趣的日期计算功能，可能是有用的，甚至我并没有可用的，在10 C 。 But the 12C has more functions than the 10B, so it’s probably better.但12 C有更多的功能，比10 B条，因此它可能更好。 The funny thing about the 12C is that I fell in love with it and I don’t even know why.有趣的事，有关12 C ，是因为我已经深深爱上了与它我什至不知道为什么。 The most important differences of the 12C probably are the many financial functions that made this model so popular, but I know nothing about them.最重要的分歧，该12 C可能是许多金融职能，使这个模式如此受欢迎，但我一无所知。 To me, the 12C just looked and felt slightly better than the other two.对我来说， 12 C只是看着，并认为稍优于其他两种。 Besides, the 12C also uses the Space key for the “equals” command in algebraic mode and the “enter” command in RPN mode.此外， 12 C也可以使用空格键为“平等”命令，在代数模式和“进入”命令，在逆波兰模式。 You certainly can see that I really like that.你当然可以看到，我真的很喜欢这一点。

THE PROBLEMS 问题

The one big, big problem with these HP emulators is how complex they are.一个大，大问题，与这些惠普模拟器是如何复杂，他们是。 Sure, you can use them for simple calculations and they look and feel great for that, but I doubt there are many people in this world who will take issue against the Blackberry calculator like I did.当然，您可以使用他们的简单计算，他们的外观和感觉非常适合，但我怀疑有很多人在这个世界上谁的问题，将采取对黑莓计算器一样，我做到了。 Most people will be 101% fine with the Blackberry calculator.大多数人将被罚款101 ％ ，与黑莓计算器。 Besides, these emulators can be dangerous in wrong hands.此外，这些模拟器可能造成危险，在坏人之手。 For example, I had to apply a little percentage calculation to an invoice I was making the other day and instead of my desktop calculators and the several manual maneuvers I usually resort to (like pencil and paper), I used my Blackberry HP emulators.举例来说，我已申请小的百分比计算，以发票我是把其他天而不是我的桌面计算机和几个手册演习，我通常会诉诸（如铅笔和纸张） ，我用我的黑莓，惠普模拟器。 The resulting calculation was wrong by a small but still relevant difference.由此产生的计算是错误的一小，但仍然相关的差异。 Luckily, I smelled something fishy in those figures and double checked them with 3 other calculators.幸运的，我闻到了一些鱼在这些数字和双重检查，他们与另外3计算器。 I probably did something wrong with the HP calculators because I can’t operate them properly.我大概做了一些错误与惠普计算器，因为我不能运作，他们妥善。 Even after I spotted the error, I still can’t figure out how to make the 12C calculate my invoice correctly.甚至后，我发现了错误，我仍然不能计算出如何使12 C计算我的发票是否正确。 There’s always an error when I add the percentage.总有一个错误的时候，我想补充的百分比。

If you’re going to buy one of these emulators, you probably want or need the complex functions, but how do you get to use them?如果您打算购买一这些模拟器，你可能想要或需要复杂的功能，但是你怎么去使用它们？ There is no documentation.有没有文件。 Each one of these emulators has a small Help screen that guides you through a few basic functions like switching from algebraic to RPN mode (it’s quite convoluted with the 10C) or increasing/reducing the number of decimal places.每一个这些模拟器有一个小屏幕上帮助指导你通过几个基本功能，如开关，从代数到逆波兰模式（它的相当错综复杂，与10 C ）或增加/减少的数目位小数。 But that’s it .但就是这样 。 Not one single word on how to perform any of the many specialized functions that each one of these little beasts are packing, not even at the Lygea Calculators’ Web site.没有一个单一的字就如何执行任何的许多专门职能的每一项这些小兽是包装，甚至没有在lygea计算器』网站。 So I did some independent searching and finally could find the original 10B and 12C manuals in PDF.因此，我做了一些独立的搜索，终于可以找到原来的10 B条和12 C手册， PDF格式。 But it was not very easy and I still haven’t found the 10C manual.但它并不是很容易的和我还没有发现10 C手册。 I think Lygea Calculators have painted themselves into a corner with that.我认为lygea计算器描绘自己成为一个角落。 In the absence of manuals, these calculators should appeal to no one but a very narrow niche where people (old people) already know how to use these calculators.在没有手册，这些计算器应该呼吁，但没有一个很窄的利基的人（旧人）已经知道如何使用这些计算机。 But if you still use one of these and you’re a professional serious enough to carry it around, you might not want to leave it home and carry just an emulator in your Blackberry because of the missing functions.但如果您仍使用上述其中一种，而您的专业严重不足，以进行它靠近，您可能不想离开它在家中进行只是一个模拟器在您的黑莓，因为该名失踪的职能。 And the young new users won’t be able to use these emulators because the functions are not documented.和年轻的新用户将无法使用这些模拟器，因为职能是没有记载。 Actually, I talked to a few eggheads before writing this review and more than one of them told me “forget these, get an HP 48 or HP 50 already” or words to that effect.其实，我跟几个eggheads前写这本审查和一个以上的，他们告诉我， “别忘了这些，获得惠普公司48或50的HP已经”或换言之即行生效。 The 10C, at least, is considered obsolete.该10 C ，至少，被认为是已经过时。 Lygea Calculators also has a 15C emulator, and my research suggests that the 15C is still quite cherished by many scientists and engineers, but Lygea Calculators does not make the 15C for the Blackberry. lygea计算器也有一个15 C模拟器，和我的研究表明，在15 C仍然是相当珍惜的许多科学家和工程师，但lygea计算器不会使15 C为黑莓。

Another problem I saw with these emulators is that they don’t offer any “history” or “ticker tape” and I think that is especially important in business and finance situations.另一个问题，我看到这些模拟器是，他们没有提供任何“历史”或“股票磁带”我认为这是特别重要的商业及金融情况。 You can copy the result from the 10C and the 12C display to the clipboard, but that’s about it.您可以复制的结果，从10 C和12 C显示到剪贴板，但的有关情况。

Last, but not least, there is no integrated conversion of measurements in any of these HP emulators.最后，但并非最不重要的，是没有综合的转换测量在任何这些惠普模拟器。 You can always look up the measurement values and calculate, but that’s not convenient by any standard.您可以随时看的测量值，并计算，但是这并不方便以任何标准来衡量。

Pros and cons: forget about it, let’s introduce a new comparison method for all of this week’s calculators: 优点和缺点：忘记它，让我们引入一个新的比较法，为所有在这个星期的计算器：

Look and feel: 10 (a lot like the physical counterparts) 外观和感觉： 10 （有很多像物理对口）

Ease of use: 7 (lack of documentation) 易于使用： 7 （缺少证件）

Math functions: 9 (or 10, maybe? They certainly can do a lot) 数学函数： 9 （或10 ，也许？他们当然可以做很多）

Data display: 8 (no full expression and no ticker tape) 数据显示： 8 （没有充分表达和NO的股票录音带）

Measurement conversion: 0 (not integrated) 度量换算： 0 （不集成）

Average: (10+7+9+8+0=34) / 5 = 6.8 平均： （ 10 7 9 8 0 = 34 ） / 5 = 6.8
