On the second day of this第二天就這 calculator roundup計算器綜述 , I went for something a little different. ，我去的東西有點不同。 The那個 HP pocket calculator emulators I discussed yesterday惠普袖珍計算器模擬器我討論昨天 are very charming and efficient, but like I said, they do have a steep learning curve.非常迷人和有效率的，但像我剛才所說，他們這樣做有一個陡峭的學習曲線。 Besides, I wasn’t really that happy with how they display data on the screen.此外，我是不是真的那麼高興與他們如何顯示數據在屏幕上。 Although I decided I liked the 12C better than the others because of the functions and put the 10C in the second place, I had a hard time letting go of the 10B because I liked the way it displayed the entire expression in one data display line.雖然我決定我喜歡12 C優於他人的，因為各項職能和把10 C在第二位，我有一個努力的時間不放的10 B條，因為我喜歡的方式顯示整個表達的一個數據顯示器產品線。 I guess I wanted that then.我猜想我想當時的。 Well, the good news is that most of the other available calculators for the Blackberry do exactly that.好，好消息是，大部分的其他可用的計算器為黑莓做的正是這一點。 The first one in that category that I tried was BizMathica .一是在這一類別中，我試圖是bizmathica 。

BizMathica will greet you with a very blank stare. bizmathica將迎來你一個很空白的凝望。 Not impressive at first.沒有令人印象深刻的在第一。 But then you just need to feed it some data.但那樣的話你只需要飼料，它的一些數據。 There is no need to press Alt or Shift keys.有沒有需要按下ALT或Shift鍵。 All numbers and symbols are recognized correctly.所有的數字和符號，是公認的正確。 And why wouldn’t they?為什麼不會呢？ That’s the only logic and sane thing to do.這是唯一的邏輯和理智的事。 Granted, you may want to type letters into an expression, like x or y, but that certainly is not the most common case.理所當然的，您可能要輸入的信件成為一個表達，如x或y ，但肯定不是最常見的案例。 If you press the 8/x key into a calculator display, chances are you want “8″, not “x”.如果您按下8 / X鍵成為一個計算器顯示，機會是您想要“ 8 ” ，而不是“ X ”的。 If you really want “x”, then you press the Alt key to type an “x”.如果你真的想的“ X ” ，那麼你就按下ALT鍵輸入一個“ X ” 。 Excellent.優秀的。 Then you press the Enter key to see the result of the expression.然後你按下Enter鍵看到的結果表達。 I didn’t like using the Enter key.我不喜歡使用Enter鍵。 I always think the Space key is a lot more comfortable and convenient for that.我一直認為，空間，關鍵是有很多更舒適和方便。 The thing is, you can actually insert spaces in the expressions although I don’t see why you would want to do that.這件事是，你其實可以插入位中的表達，雖然我不明白為什麼你會想這樣做。

Symbols are typed immediately as long as they are available in the keyboard.符號輸入立即只要他們都可以在鍵盤上。 If they’re not, you can also resort to the Blackberry’s own Symbol key and get more symbols.如果他們不，您也可以訴諸黑莓自己的符號的關鍵，並獲得更多的符號。 And another very good thing about expression input in BizMathica is that correct operation precedence is applied.另一個很好的事，關於表達的投入bizmathica是正確的行動，優先適用。 I我 mentioned this problem when I reviewed the HP 10B pocket calculator emulator提到這個問題，當我回顧了惠普公司10 B條，袖珍計算器模擬器 : you key in 22*16+4*2 into the HP 10B and the result is 712 when you probably expect 360.問：您的關鍵在22 * 16 4 * 2到惠普10 B條和結果是712時，你可能預期360 。 In BizMathica , the result of that expression is 360.在bizmathica ，結果所表達的是360 。 You may want to enclose certain operations in parentheses like this: (22*16)+(4*2).您可能要附上某些業務括號內是這樣的： （ 22 * 16 ） + （ 4 * 2 ） 。 But it’s not necessary.但它沒有必要的。 The result is 360 either way.結果是， 360無論哪種方式。

BizMathica doesn’t look very good at first sight, but there is something very clever about this type of calculator that no one can deny: the phone already has keys with numbers and math symbols. bizmathica看來並不樂觀很好的驟眼看來，但有一些很聰明的關於這種類型的計算器說，沒有人可以否認：手機已鍵與數字和數學符號。 Why clutter the screen with fake keys?為什麼雜波屏幕與假鑰匙呢？ Why not use the entire screen space to display more data?為什麼不使用整個屏幕空間來顯示更多的數據？ What is this?這是什麼？ An iPhone?一個擁有呢？ Certainly not, so there is plenty of screen real state for data display.當然不是，所以有足夠的屏幕上實時狀態數據顯示。 So all you have to do is press Enter and there is your result, and not only that, you can always refer to many if not all of the previous operations.因此，所有您需要做的就是按下ENTER ，並有您的結果，不僅如此，您可以隨時參閱許多如果不是全部的前行動。 They’re all sent to the “history” area above the current expression and you can have a pretty long history.他們都是發送到“歷史”方面高於目前的表達，你可以有一個相當長的歷史。 The length of the history is configurable and the default is 150 lines.長度的歷史，是配置和預設值是150線。 I wonder if there is too much of a performance impact if I raise it to, say, 500.我不知道，如果有太多表現的影響，如果我提出來，也就是說， 500 。 It is possible.這是可能的。 I changed mine to 1,500 and there was no error message regarding any limits.我改變礦井1500並沒有錯誤訊息就任何限制。 You can scroll all that you want through that operation history and, of course, copy the whole of it so as to paste it elsewhere.您可以滾動所有您想要通過這一行動的歷史，當然，複製整個資訊科技，以便將其粘貼在其他地方。 Remember: not an iPhone.請記住：沒有一個擁有。

Note that the result is displayed twice: immediately below the last expression and at the bottom of the screen.請注意，結果顯示兩次：立即低於去年的表達及在屏幕的底部。 No matter what you do, the bottom of the screen always displays the result of the last expression.不管你這樣做，屏幕的底部總是顯示的結果，最後的表達。 That’s probably a reminder because you can always use that last result in your next operation.這也許是提醒，因為你可以一直使用，去年的結果在您下次的行動。 All you have to do is type the “@” symbol into your expression and it will be calculated as the value obtained from the last calculation.所有您需要做的就是輸入“ @ ”符號到您的表達，並會計算的價值從去年的計算方法。 Look at these screnshots:看看這些screnshots ：

The “@” symbol is a “global parameter”, which happens to be variable. “ @ ”符號是一個“全球參數” ，這剛巧是變數。 Other “global parameters” are fixed.其他“全球參數”是固定的。 You can add your own and edit the existing ones in the configuration section:您可以添加自己和編輯現有的在配置節：

If you look closely, you should see ExchgRateToHome and ExchgRateToOther .如果你仔細看看，您應該會看到exchgratetohome和exchgratetoother 。 That is supposed to be used in currency exchange rate conversions, but I don’t see how that can be really useful since there is no currency update mechanism.這是假定將用於在貨幣匯率轉換，但我看不出如何能真正有用，因為是沒有貨幣的更新機制。 The only value it has is the ability to be edited and used in whatever way you may come up with and apply conversions.唯一的價值，這已是能夠加以編輯和使用的方式，你可能會與和適用的轉換。

IF YOU MEAN BUSINESS 如果你的意思業務

Scientific and financial calculators die-hards may be wondering about how to perform all those specific functions with BizMathica , but they probably have seen the screenshots and noticed those two Functions and Formulas lines.科學和金融計算器壓鑄hards可能想知道有關如何執行所有這些具體職能與bizmathica ，但他們可能看到了畫面，並注意到這兩個功能和公式線。 Those are menus.這些都是菜單。 They contain many formulas and functions that you can use and edit/customize if you want.它們包含許多公式和功能，您可以使用和編輯/自定義如果你想。 I am not sure how well and to what extent those formulas can be customized.我不知道如何以及在何種程度上，這些公式可以自訂。 In fact, I found that option very confusing.事實上，我發現，選擇非常混亂。 Still, even if you can’t change it just the way you want, by all means check this還有，即使你不能改變它只是您想要的方式，運用一切手段，請在此 neverending list of formulas and functions neverending名單公式和職能 at ShrunkenHead’s site.在shrunkenhead的網站。 There are both scientific and financial functions in that list, and there is a lot of them.有科學和財務職能在該名單中，有很多他們。

You will probably have to check the你可能會檢查 manuals in PDF手冊PDF格式 to master these more advanced features.掌握這些更先進的功能。 I didn’t.我沒有。 But I bet that should be a lot less reading than the typical 200-page manuals of the HP calculators - if you can find them.但我敢打賭，應該少很多讀，比典型的200頁的手冊惠普計算器-如果你能找到他們。 The HP calculators are complex all-around unless you’re already very familiar with them whereas BizMathica has only a few arcane features that are likely to require some reading.惠普計算器是複雜的全約，除非您已經很熟悉他們，而bizmathica已只有少數難懂的功能是可能需要一些讀。

THE PROBLEMS 問題

OK, enough with the nice words.確定，足以與好話，動聽的話。 Let’s now see what is very, very wrong with this calculator.讓我們現在看到的是什麼是非常，非常不妥，這計算器。 By far, the absolutely worst thing about this calculator is the whole interface beyond the basics.到目前為止，絕對是最糟糕的事對這個計算器是整個界面除了基礎。

First off, how come there are two menus, one for formulas and one for functions?首先，如何來有兩個菜單，一個公式和一個功能？ Whenever I want to use one of them, I’m never sure whether it is a formula or a function and often waste time looking for it in the wrong menu.每當我要使用的其中一人，我從來沒有肯定是否這是一個公式或函數，而且往往浪費時間尋找它在錯誤的菜單。 It’s confusing!它的混亂！

Then suppose you have the right menu.然後假設您有權利菜單。 How do you use it?你怎麼使用它？ Pay attention: if you click the trackball in the big expression area, you get a certain generic menu.注意：如果您按一下軌跡球在大面積的表達，您會獲得一定的通用菜單。 If you click the Formulas or Functions menu with the trackball, you don’t get a list of formulas/functions, you get that same generic menu.如果您單擊公式或功能菜單與軌跡球，你沒有得到的名單公式/職能，您會獲得同樣的通用菜單。 Awful!可怕的！ In order to select a formula/function, you’ll have to scroll down to “Change option” in the generic menu and click “Change option”.在以選擇一個公式/功能，您必須向下滾動，以“變更選項： ”在通用菜單，並點擊“更改選項” 。 Then you’re shown the formula or function menu.然後您顯示公式或功能菜單。 Really awful!真正可怕的！ And when you find the item you want, you don’t just click it.和當您找到您想要的項目，你不只要按一下它。 After you click it, you still have to press the Enter key or the trackball and select “Copy To” from the menu that ensues.當您按一下它，你仍然要按下Enter鍵，或軌跡球並選擇“複製”從菜單中ensues 。 Unbelievably awful!令人難以置信的可怕！

There is a shortcut.有一個捷徑。 Highlight one of those Formulas or Functions menus and press the first letter of the formula/function you want.突出的一個，這些公式或功能菜單和新聞界的第一個字母的公式/您想要的功能。 That will be faster… if you’re smarter than I am and never have any doubts whether what you want is a formula or function and never pick the wrong menu.這將是更快…如果您聰明，比我還從未有任何懷疑，是否有什麼你想要的是一個公式或函數和從來沒有選擇錯誤的菜單。

And sometimes the formula/function is quite dumb and requires way too much clicking and scrolling.有時公式/功能是相當愚蠢的方式，並要求太多的點擊和滾動。 Let’s see one example: how many kilograms are there in 200 pounds?讓我們看看一個例子：有多少公斤是否有在200磅？ Look at the screenshots before I explain:看看在畫面之前，我解釋：

The screenshots above demonstrate “the wrong way”: you don’t know how many kilograms it’s going to be, but you can’t leave it empty.截圖上述證明“錯誤的方式” ：你不知道有多少公斤，它的去，但你不能離開它是空的。 Why not?為什麼不呢？ What else could someone ever type in there?還有什麼能夠有人以往任何時候都在有型呢？ Heck if I know.赫克如果我知道。 You just can’t leave it empty.剛才你不能離開它是空的。 But typing anything there doesn’t make any sense, does it?但打字有什麼不作任何意義，不是嗎？

Of course it doesn’t!當然，這不！ But just look at how many things are wrong with it:但只要看看有多少事情是錯的，與它：

1. I can’t leave the result field empty.我不能離開的結果字段留空。
2. What is the deal with the OK and Cancel buttons?什麼是處理與確定和取消按鈕？ If I press Enter, I should get the result immediately so it is faster .如果我按下ENTER ，我應該得到立即的結果，所以這是更快 。 I can always cancel the operation with the phone’s Escape key.我可以永遠取消操作與手機的逃生的關鍵。 I’ve lost count of how many times I pressed that Cancel button by mistake!我失去了指望有多少時候，我按下認為，取消按鈕的錯誤！
3. Instead of getting the result right away, I have to press the OK button.而不是得到的結果，馬上，我要按下OK按鈕。
4. Even after I press the OK button, I still don’t get the result!甚至當我按下確定按鈕，我仍然沒有得到結果！ I get an expression and have to press Enter.我得到一個表達，並須按下ENTER 。
5. Only after I press Enter, I am told in a rather obscure way that I made a mistake several steps ago that the application would rather point out now and not then .只有當我按下ENTER ，據我所知，在一個相當模糊的方式，我犯了一個錯誤，幾個步驟前，應用寧願指出， 現在不是那麼 。

What is the right way, then?什麼是正確的做法，然後呢？

All that trouble because of a “?” symbol!所有的麻煩，因為一個“ ？ ”的象徵！ OK, I’ve learned it, no more error messages.確定，我已經學會它，沒有更多的錯誤訊息。 But I am still forced to fill in an unnecessary field and the correct filling of this field will not prevent all the rest of the remarkably convoluted process.但我仍被迫以填補在不必要的領域和正確的填補這一領域的將不能防止所有其餘的顯著錯綜複雜的過程。

In fewer words: accessing and using formulas and functions (like measurement conversions) with BizMathica is a major pain .在較少的話：訪問和使用公式和職能（如測量轉換）與bizmathica是一個重大的痛苦 。 This is one excellent example of the many situations that make me wonder what in the blue blazes goes on the minds of the developers that come up with these awful interfaces and incredible procedures.這是一個很好的例子，許多情況下，使我不知道是什麼在藍色的火光下去，頭腦中發展而來的，與這些可怕的界面和令人難以置信的程序。 Oh, well.哦，好。 Not an iPhone, I guess.不是擁有，我猜想。 All these years and Apple has taught nothing to these people.所有這些年來，蘋果給無關，這些人。

Pros and cons: I find it too difficult to sum them up. 優點和缺點：我覺得這太困難，總結起來。 Don’t be so lazy, read the article.不那麼懶惰，閱讀文章。 Instead, I’ll just apply the single comparison method I chose for all of this week’s calculators:反之，我將只適用於單一的比較方法我選擇了為所有在這個星期的計算器：

Look and feel: 6 (look is just OK, feel not so much) 外觀和感覺： 6 （看看是剛剛確定，覺得沒有這麼多）

Ease of use: 7 (the interface is not intuitive in several details, too many design blunders) 易於使用： 7 （接口是不直觀的在幾個細節，有太多的設計失誤）

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

Data display: 10 (full expressions and ticker tape) 數據顯示： 10 （充分的表達和股票錄音帶）

Measurement conversion: 7 (it’s there, but lacks useability and there are not that many measurement units) 度量換算： 7 （它的存在，但缺乏useability有沒有那麼多的測量單位）

Average: (6+7+9+10+7=39) / 5 = 7.8 平均： （ 6 7 9 10 7 = 39 ） / 5 = 7.8
