On the first day of this series, I’ll present three calculators already.第一天就這一系列，我會目前已經3計算器。 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.其中的第一件事我參加成，而狩獵計算機應用服務，在berryreview商店是這條路線的惠普公司袖珍計算器模擬器由lygea計算器。 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 .他們是為了學習更多或更少相同的外觀和功能的三個經典惠普型號： 10 B條 ， 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.他們都有非常具體的職能，可能對某些問題的學生或專業人士，但他們仍然分享足夠的相似性，我整他們都一起在一個單一集團。

THE 10B “BUSINESS” CALCULATOR 該10 B條“業務”計算器

The 10B (”B” as in “Business”) is the one that looks the least like its physical counterpart.該10 B條 （有“ B ”作為在“業務” ）是一個看起來最不發達國家一樣，其物理對應。 Click the picture to see it in full size.點擊圖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條，有一個垂直佈局已能適應黑莓曲線的橫向屏幕。 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，佈局要改變一點，因為屏幕太小，適合所有的鑰匙和職能。 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.所以我猜的許多功能已被犧牲和它的，我很難分辨哪些是因為我不熟悉，在所有與此計算器。 All I can say about it is from the point of view of someone who is just looking for a better calculator.我所能說的大約是從的角度來看，有人誰是只看一個更美好的計算器。

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.無論杭的UPS ，我與黑莓計算器不適用本惠普10 B條模擬器。 This one really looks and feels like a calculator and I think I could actually have fun punching numbers into it.此一真正的外表和讓人感覺更像是一個計算器，我想我真的可以得到樂趣沖壓號碼到它。 I was surprised because it displays the whole operation/expression in the display.我很驚訝，因為它顯示整個運作/表達在顯示器上。 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，您的關鍵在22 * 16 4 * 2 ，這整個的表達將顯示在一個單一線，直到您回車鍵/平等的，並得到運算結果。 I found that very pleasant visually.我發覺非常愉快的視覺效果。 I get to see whatever is actually being calculated.我要見什麼，其實是被計算出來的。 There is one problem, though: precedence.有一個問題，雖然：優先。 This calculator does not apply any precedence to the operations so 22*16+4*2 equals 712 when you probably expect 360.這計算器並不適用於任何優先的行動，使22 * 16 4 * 2等於712時，你可能預期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（誰不？ ） ，您都必須附上行動在括號： （ 22 * 16 ） + （ 4 * 2 ） 。 Then you’ll get 360.然後您將獲得360 。 That kind of put me off.那種把我趕走。 It’s just not the right thing to do in an expression.它的正義不是正確的事，在一個表達式。 Another problem is the equals sign is tucked in the corner of the layout.另一個問題是，等號是藏在角落的佈局。 That may not seem a big deal at first, but it does get annoying after a while.可能似乎不是一個很大的處理，在第一，但它確實讓惱人的後一段時間。 That corner is too far.那個角落是太遠。

This business calculator probably supports a lot of functions I am not famliar with so I didn’t even bother testing them.這項業務的計算器可能支持了很多功能，我不famliar那麼我什至沒有理會他們的測試。 I can only assume that at least the functions you can see in the keyboard/layout are fully supported.我只能假設說，至少有職能，你可以看到，在鍵盤/佈局的充分支持。 I will discuss the issues in relation to the manual and information later in this article.我將討論這些問題在有關手冊和資料，後來在這方面的文章。 Meanwhile, you can check a summary of its functions同時，您可以檢查的總結其職能 here這裡 . 。

THE 10C SCIENTIFIC CALCULATOR 該10 C科學計算器

The 10C is a scientific calculator and it looks quite a lot like its physical counterpart.該10 C是一個科學的計算器和看來，不少像其物理對應。 Click the picture to see it in full size.點擊圖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，它看起來像數職能已犧牲了，也許因為沒有空間，他們都在鍵盤/佈局，或者因為它是太困難，加以實施。

I couldn’t help comparing the 10C with the 10B.我不能幫助比較， 10 C與10 B條。 The 10C looks more “complete” to me, but probably only because I have a stronger identification with scientific calculations than with business calculations.該10 C看起來更“完整”給我，但可能只是因為我有較強的識別與科學計算，比與商業計算。 I actually studied a little engineering in College, when I was a lot younger.其實，我研究了小工程在高校，當我是一個有很多年輕。 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.在其他換言之，這其中有很多支持更多的功能，我所熟悉的不是很多職能的10 B條，完全我大惑不解。 It will depend a lot on what you do, what you need, what you want.這將取決於很多對你這樣做，您所需要的，你想要的。 Meanwhile, you can check a summary of its functions同時，您可以檢查的總結其職能 here這裡 . 。

Another important distinction of the 10C is the support to RPN, which helps a lot with the precedence problem.另一個重要的區別的是10 C的支持，以逆波蘭，其中有很大幫助與優先問題。 Who needs parentheses when you have RPN?誰需要括號時，你有逆波蘭？ On the other hand, RPN is all you have with the 10C .在另一方面，逆波蘭是所有您已經與10 C 。 The algebraic mode is not supported.代數模式是不支持。 This is obviously not a calculator for ordinary citizens to calculate their gas, income tax or keep track of their expense at the supermarket.這顯然不是一個計算器，為普通公民來計算他們的氣，入息稅或跟踪他們的犧牲是在超級市場。 This calculator packs too many functions that only specialized people are likely to be interested in.這計算器包太多的職能，只有專門的人很可能會感興趣

What pleased me most about the 10C was that I could finally use the Space key for the “equals” command.有什麼高興我最關心的10 C是，我終於可以使用空格鍵為“平等”命令。 Well, not quite since it’s RPN only so it’s actually the “enter” command.好，不大，因為它的逆波蘭只有這樣，它的實際上是“進入”命令。 All the same, I like it.所有相同的，我喜歡它。

THE 12C FINANCIAL CALCULATOR 該12 C金融計算器

The original HP 12C enjoys stardom status among all pocket calculators.原惠普12 C享有的明星地位，各袖珍計算器。 It’s still widely used in its physical form, apparently.它的廣泛使用，仍然在其實物形式，顯然。 The 12C emulator is a financial calculator that also looks quite a lot like its physical counterpart.該12 C模擬器是一個金融計算器，也期待了不少像其物理對應。 Click the picture to see it in full size.點擊圖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 ，它看起來像數的職能已被犧牲。 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條。 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.我試圖檢查仔細，但原來，這是混淆我，因為我不是在所有熟悉所有這些財政的職能和運作。 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.我決定，我根本沒有資格不夠的法官，除非我只是看看她的立場，從一個門外漢在尋找更好的計算器。 There is a summary of the 12C functions有一個總結了12 C的職能 here這裡 . 。

The 12C supports both algebraic and RPN modes, so it is prone to please a wider audience.該12 C既支持的代數和逆波蘭模式，因此它很容易，請更廣泛的觀眾。 Whichever you choose, it will be there after you close the application and launch it again.無論您選擇，這將有後，您關閉應用程式，並再次啟動它。 What will not be there, however, is the stack display if you switch from RPN to algebraic.什麼將不會有，不過，堆棧顯示如果您切換從逆波蘭以代數。 Switch back to RPN and the stack will be gone, and enabling it again is a little annoying.切換回逆波蘭和堆棧將會消失，並使它再次是有點惱人。 But I guess most users will just pick algebraic or RPN and commit for life.但我估計大多數用戶只需選擇代數或逆波蘭，並承諾終身。

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 .作為一個門外漢，我看到這10 B條和12 C都支持很有趣的日期計算功能，可能是有用的，甚至我並沒有可用的，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條，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，有關12 C ，是因為我已經深深愛上了與它我什至不知道為什麼。 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，該12 C可能是許多金融職能，使這個模式如此受歡迎，但我一無所知。 To me, the 12C just looked and felt slightly better than the other two.對我來說， 12 C只是看著，並認為稍優於其他兩種。 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也可以使用空格鍵為“平等”命令，在代數模式和“進入”命令，在逆波蘭模式。 You certainly can see that I really like that.你當然可以看到，我真的很喜歡這一點。

THE PROBLEMS 問題

The one big, big problem with these HP emulators is how complex they are.一個大，大問題，與這些惠普模擬器是如何複雜，他們是。 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.當然，您可以使用他們的簡單計算，他們的外觀和感覺非常適合，但我懷疑有很多人在這個世界上誰的問題，將採取對黑莓計算器一樣，我做到了。 Most people will be 101% fine with the Blackberry calculator.大多數人將被罰款101 ％ ，與黑莓計算器。 Besides, these emulators can be dangerous in wrong hands.此外，這些模擬器可能造成危險，在壞人之手。 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.舉例來說，我已申請小的百分比計算，以發票我是把其他天而不是我的桌面計算機和幾個手冊演習，我通常會訴諸（如鉛筆和紙張） ，我用我的黑莓，惠普模擬器。 The resulting calculation was wrong by a small but still relevant difference.由此產生的計算是錯誤的一小，但仍然相關的差異。 Luckily, I smelled something fishy in those figures and double checked them with 3 other calculators.幸運的，我聞到了一些魚在這些數字和雙重檢查，他們與另外3計算器。 I probably did something wrong with the HP calculators because I can’t operate them properly.我大概做了一些錯誤與惠普計算器，因為我不能運作，他們妥善。 Even after I spotted the error, I still can’t figure out how to make the 12C calculate my invoice correctly.甚至後，我發現了錯誤，我仍然不能計算出如何使12 C計算我的發票是否正確。 There’s always an error when I add the percentage.總有一個錯誤的時候，我想補充的百分比。

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?如果您打算購買一這些模擬器，你可能想要或需要複雜的功能，但是你怎麼去使用它們？ There is no documentation.有沒有文件。 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.每一個這些模擬器有一個小屏幕上幫助指導你通過幾個基本功能，如開關，從代數到逆波蘭模式（它的相當錯綜複雜，與10 C ）或增加/減少的數目位小數。 But that’s it .但就是這樣 。 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.沒有一個單一的字就如何執行任何的許多專門職能的每一項這些小獸是包裝，甚至沒有在lygea計算器』網站。 So I did some independent searching and finally could find the original 10B and 12C manuals in PDF.因此，我做了一些獨立的搜索，終於可以找到原來的10 B條和12 C手冊， PDF格式。 But it was not very easy and I still haven’t found the 10C manual.但它並不是很容易的和我還沒有發現10 C手冊。 I think Lygea Calculators have painted themselves into a corner with that.我認為lygea計算器描繪自己成為一個角落。 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.在沒有手冊，這些計算器應該呼籲，但沒有一個很窄的利基的人（舊人）已經知道如何使用這些計算機。 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種，而您的專業嚴重不足，以進行它靠近，您可能不想離開它在家中進行只是一個模擬器在您的黑莓，因為該名失踪的職能。 And the young new users won’t be able to use these emulators because the functions are not documented.和年輕的新用戶將無法使用這些模擬器，因為職能是沒有記載。 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.其實，我跟幾個eggheads前寫這本審查和一個以上的，他們告訴我， “別忘了這些，獲得惠普公司48或50的HP已經”或換言之即行生效。 The 10C, at least, is considered obsolete.該10 C ，至少，被認為是已經過時。 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計算器也有一個15 C模擬器，和我的研究表明，在15 C仍然是相當珍惜的許多科學家和工程師，但lygea計算器不會使15 C為黑莓。

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.另一個問題，我看到這些模擬器是，他們沒有提供任何“歷史”或“股票磁帶”我認為這是特別重要的商業及金融情況。 You can copy the result from the 10C and the 12C display to the clipboard, but that’s about it.您可以複製的結果，從10 C和12 C顯示到剪貼板，但的有關情況。

Last, but not least, there is no integrated conversion of measurements in any of these HP emulators.最後，但並非最不重要的，是沒有綜合的轉換測量在任何這些惠普模擬器。 You can always look up the measurement values and calculate, but that’s not convenient by any standard.您可以隨時看的測量值，並計算，但是這並不方便以任何標準來衡量。

Pros and cons: forget about it, let’s introduce a new comparison method for all of this week’s calculators: 優點和缺點：忘記它，讓我們引入一個新的比較法，為所有在這個星期的計算器：

Look and feel: 10 (a lot like the physical counterparts) 外觀和感覺： 10 （有很多像物理對口）

Ease of use: 7 (lack of documentation) 易於使用： 7 （缺少證件）

Math functions: 9 (or 10, maybe? They certainly can do a lot) 數學函數： 9 （或10 ，也許？他們當然可以做很多）

Data display: 8 (no full expression and no ticker tape) 數據顯示： 8 （沒有充分表達和NO的股票錄音帶）

Measurement conversion: 0 (not integrated) 度量換算： 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
