This the third day of the这第三天的 calculator roundup计算器综述 . 。 My sincere apologies to the readers who were following the series last week and were disappointed at the lack of “episodes”.我真诚地道歉，向读者谁被以下的一系列上周和失望，在缺乏“发作” 。 I was left alone here at BerryReview to post the “news” while everyone else was out having fun most of the week, so I just didn’t have time to finish the reviews.我是独自在这里berryreview发布“新闻” ，而其他人是出于玩乐，大部分的周，所以我只是没有时间去完成审查。 Life goes on.生活继续下去。

But I still have a little bit of disappointment in store for you.但我仍然有一点点失望，在商店为您。 Today I am going to review今天我要检讨 BKGcalc bkgcalc , probably the worst of all calculators of this roundup. ，可能是最坏的所有计算机，这个综述。 It has none of the flare of the HP pocket calculator emulators I有没有该耀斑的惠普袖珍计算器模拟器i discussed last Monday讨论上周一 . BKGcalc is a lot like 。 bkgcalc是很多想 BizMathica bizmathica in look and behavior, and it is quite powerful too, but with even more flaws.在外观和行为，这是相当强大的太多，但更缺陷。 Enough of them to quite ruin my experience with it.受够了他们不少破坏我的经验与它。

The first alarms ring right at the store front.第一次警报响的权利，在商店前面。 First, at $3.95, it’s remarkably cheaper than the other calculators.首先，在$ 3.95 ，它的显着便宜，比其他计算机。 You have to wonder why.你必须想知道为什么。 Then you can see this warning at the top of然后你可以看到这样的警告在其顶部 one of the main information pages其中一个主要的信息页面 : ：

The mathematical models - though seemingly accurate - have not been tested to the level one would require for importiant (sic) matters involving life-and-limb, finances, etc. This software is proved for “entertainment purposes only”, and is given “AS-IS” with no warranty expressed or implied.数学模型-虽然看似准确的-没有经过测试，以水平一将需要为i m portiant（原文如此）的事项，涉及生命和肢体，财政，等这个软件是证明了“娱乐的目的，只有”，并给出了“ -是“没有保修明示或默示的。 On second thought, it probibly (sic) doesn’t work at all.关于第二个思想，它probibly （原文如此）不工作。 Go use an abicus (sic) or something instead.去使用abicus （原文如此）或一些不是。

Way to make a sale!的方式作出出售！

Just like就像 BizMathica bizmathica , BKGcalc will greet you with a very blank stare. ， bkgcalc将迎来你一个很空白的凝望。 Not impressive at first.没有令人印象深刻的在第一。 Oh, right, you just need to feed it some data… And that’s when most of the trouble begins!哦，正确的，你只需要饲料，它的一些数据… …并指出，当大部分的麻烦开始了！ BizMathica does not require you to press Alt or Shift keys. bizmathica不会要求您按下ALT或Shift键。 All numbers and symbols are recognized correctly. BKGcalc does! BKGcalc is completely oblivious to the fact that this a freaking calculator.所有的数字和符号，是公认的正确。 bkgcalc不！ bkgcalc ，完全是无视事实，即这是一个再用计算器。 Why would I ever want to type letters into it?为何我会以往任何时候都需要输入的信件到它呢？ Granted, you may want to type letters into an expression, like x or y, but that is the exception, not the rule!理所当然的，您可能要输入的信件成为一个表达，如x或y ，但这是例外，而不是法治！ Let’s make this long story short: it sucks.让我们使这个长期的故事，一句话：它sucks为。 My first impulse was to press Alt to reach each number.我的第一个冲动是要按下ALT达到每个数字。 Of course, doing that for each digit is stupid.当然，这样做，为每个数字是愚蠢的。 So I “locked” the phone into numeric mode and it got better.因此，我“锁定”电话到数字模式，并得到更好的。 But that was an awful arrangement.不过，这是一个可怕的安排。 First, I always forget to lock it into numeric mode.首先，我总是忘了锁成数字模式。 So I always end up calling the application a few bad names before plunging into the number crunching.所以，我总是最后要求的应用的几个坏的名称之前，陷入人数业绩。 Then I forget to unlock the numeric mode and have a similar problem with whatever application I tried to use next.然后我忘记了解锁的数值模式和有类似问题的应用，无论我尝试使用下一步。 Grrr… They really messed up with this keyboard mode input thing.哎呀… …他们真的搞砸这个键盘输入模式的事。 Moreover, the num lock mode is lost if you put the Blackberry into a magnetic holster then take it out again.此外，的NUM LOCK模式是失去如果你把黑莓成为一个磁holster ，然后采取它再次。 No kidding, just try it yourself.没有开玩笑，只是亲身体验。 Trouble, trouble, trouble.麻烦，麻烦，麻烦。

If you’re less picky than me and can get past this major inconvenience, then you’re left with quite a powerful calculator.如果您少挑剔，比我过去可以得到这一重大的不便，那么您留下相当强大的计算器。 It’sa lot like BizMathica: just enter full expressions and hit the Enter key to get the result of each expression.这是很多想bizmathica ：只要输入充分的表达，并撞向Enter键就可以得到的结果，每个表达。 Those results “accumulate” in a sort of ticker tape history that can be copied and pasted elsewhere.这些成果的“积累”在一种代号磁带的历史可以复制并粘贴在其他地方。 Two differences between BizMathica and BKGcalc were instanly noticeable as soon as I started the test: first, BKGcalc does not apply proper operation precedence.二之间的分歧bizmathica和bkgcalc被instanly显着尽快我开始测试：第一， bkgcalc并不适用于适当的运作先例。 In other words, (22*16+4*2) does NOT yield the same result as (4*2+22*16) unless you separate multiplications with parentheses: ((22*16)+(4*2)).在其他的话， （ 22 * 16 4 * 2 ）不会产生相同的结果（ 4 * 2 22 * 16 ） ，除非你单独的乘法与括号： （ （ 22 * 16 ） + （ 4 * 2 ） ） 。 Note that you also must be in num lock mode to type in the parentheses.请注意，您也必须在的Num Lock模式类型，在括号中。

The second difference is that BKGcalc also has a “global parameter” to represent the “last result” (ans in BKGcalc , the @ symbol in BizMathica), it is not really necessary.第二个不同的是， bkgcalc也有一个“全球性参数”代表“最后结果” （答在bkgcalc ， @符号在bizmathica ） ，这是不是确有必要。 You can just type an operator sign before a number or expression and it will be applied to the last result automatically.您可以只需键入一个运营商签署前一个号码或表达，并会应用到最后的结果，自动。

What BizMathica calls “global parameter”, BKGcalc calls “variables”.什么bizmathica呼吁“全球参数” ， bkgcalc所谓的“变数” 。 You can’t create or edit them.你不能创建或编辑。 If you visit that如果您的访问 the reference page参考网页 , you should see mention of the ability to create/edit variables and functions, but that is promised for version 1.1, not available yet. ，您应该可以看到一提的能力，创建/编辑的变数和职能，不过，这是承诺的1.1版，还没有。 I found that rather annoying.我发现，而不是烦人的。 That specific ability sounded interesting to me, and the words “New in Version 1.1″ next to the description of such feature made me assume that 1.1 was indeed the latest version.具体的能力，吹响了有趣的我，改为“在新的1.1版”旁边的说明，这样的功能，使我以为1.1的确是最新的版本。 But it isn’t.但事实并非如此。 I actually bought BKGcalc and only after I had it I saw that 1.0 was the only version available.其实，我买了bkgcalc后，才和我有它我看到1.0是唯一版本。 I contacted the author on March 27 (more than 30 days ago) and never had any reply.我所接触的作者3月27日（ 30天以上前）和从未有过任何答复。

BKGcalc supports a good number of functions like BizMathica, but I don’t think they are that many. bkgcalc支持相当数量的功能，如bizmathica ，但我不认为他们是很多。 You can read您可以阅读 the reference page参考网页 and compare and take your own conclusions.和比较，并采取您自己的结论。 Besides, you have to type them manually.此外，你必须键入他们手动。 For example, to calculate the cosine of 45, you have to type cos(45) then hit Enter.举例来说，计算余弦45 ，你必须键入产地来源证（ 45 ） ，然后按下Enter键。 To get the square root of 169, you must type sqrt(169), and so on.得到的平方根169 ，你必须键入sqrt （ 169 ） ，等等。 Then the absence of a default num lock mode begins to make sense.然后没有一个预设的Num Lock模式开始作出意识。 But I don’t think I like it.但我不认为我喜欢它。 I guess it would take a long time until I memorized which functions are available or not.我猜想，这需要很长的时间，直到我背哪些职能是提供或没有。 BizMathica at least gives us a list to choose from. bizmathica至少给我们的名单选择。 However, BizMathica function/formula menus are undoubtedly awkward and inconvenient.不过， bizmathica职能/公式菜单，无疑是尴尬和不便。 When I think of that, typing expressions into BKGcalc doesn’t sound so bad.当我想到这一点，打字表达到bkgcalc不健全的那么差劲。 So the jury is still out on which one has the worse implementation, BizMathica or BKGcalc .因此，陪审团仍然列于其中有更糟的实施， bizmathica或bkgcalc 。 The jury has decided, though, that both approaches suck.陪审团已决定，虽然，这两种方法的吸吮。

What BKGcalc has that the others don’t is some sort of idiosyncratic “Engineering Base”.什么bkgcalc已表示，别人不某种特质“工程基地” 。 Here is the author’s explanation in his own words:这里是作者的解释，他自己的话说：

BKGcalc will take input, and display out (when in “eng” mode) using some of the standard numerical suffixes - ie “k” for 1000, “M” for 1000000, etc. This often makes things more ledgible, and easier to type. bkgcalc将采取投入，并显示出来（当在“工程”模式） ，使用一些标准的数值后缀-即和“ K ”为1 000年， “男”为1 00.0万，等这往往使事情更l edgible，并更容易类型。

However - in the world of computers “k” isn’t 1000 - it’s 1024 and “M” isn’t 1000000 - it’s 1048576 (1024*1024), etc. So to make life a bit easier in doing computer-work “comp” mode treats these suffixes - in both display and data entry as 1024-based - not the usual 1000-based.不过-在世界上的电脑和“ K ”是不是1 000年-它的1 0 24年和“米”不是百万-它的1 0 4 8576（10 2 4*10 2 4）等，以便使生活有点容易在这样做的电脑-工作“补偿”的模式对待这些后缀-在这两个显示器和数据录入，作为1 024年为基础的-而不是通常的1 0 00为基础的。 So these symbols have meanings which depend on the mode you’re in.因此，这些标志的含义依赖于模式，您英寸

An interesting feature.一个有趣的功能。 But a very personal approach, in my opinion.但一个非常个人的做法，在我的意见。 You could love it or simply ignore it, either way.你可以爱它，要么干脆不理会它，无论哪种方式。

The last thing to consider in BKGcalc is the measurement conversion feature.最后要考虑在bkgcalc是测量转换功能。 I didn’t like it at all.我不喜欢它在所有。 It’s more or less as bad as or maybe even a little worse than that of BizMathica.它的更多或更少恶劣，或者甚至有点不如的bizmathica 。 First, you type a number or simply reuse the last expression’s result automatically.首先，您可以输入一个号码或简单地再用过去表达的结果自动。 Either way, as soon as you have a number in the last line, you click the trackball and call up the menu and select “Convert…” You will see your number and a series of drop-down menus.无论采用哪种方式，当您有一些在最后一行，您按一下轨迹球，并呼吁加快菜单，并选择“转换… … ” ，您会看到您的电话号码，以及一系列的下拉式选单。 Then you choose a conversion category (angle, area, distance etc.) Then you choose the measurement unit you have, eg pounds.然后你选择一个转换类（角度，面积，距离等） ，然后您选择的测量单位，你有，例如英镑。 Then you choose the desired measurement unit of your conversion, eg kilograms.然后，您可以选择理想的计量单位的转换，如公斤。 Then you see an OK button.然后您会看到一个OK按钮。 What would any intellingent human being instantly assume?会有什么任何智能的人立即承担？ That you’re supposed to click OK to get the result of the conversion, right?您要单击确定以取得的结果，转换，对不对？ But noooo… That will give you a menu with a whopping ONE choice: “Full Menu”.但noooo …这会给你一个菜单与高达一个选择： “充分菜单” 。 Isn’t that lovely?是不是可爱的呢？ And no one can ever be prepared for the whopping number of choices the next menu will bring: ONE: “Close”.没有人可以任何时候都准备为高达数目的选择，未来会带来菜单： 1 ： “关闭” 。 Close the darn thing and you’re back to the previous calculation screen, this time with the result inserted into the last (result) line.关闭石坝的事情，您回到以前的计算屏幕上，这个时候与结果插入到最后（结果）线。 OK, I eventually learned: once you have picked the two measurement units, you’re supposed to exit that conversion screen.确定，我最终的教训：一旦你选择了两个计量单位，您要退出 ，转换屏幕上。 So the Blackberry’s escape key will suffice.因此，黑莓的逃生的关键将是不够的。 But that kind of design is absolutely appalling.但这种设计是绝对令人震惊。 Well, BizMathica is not much better either.那么， bizmathica是不是好得多。

THE PROBLEMS 问题

Are you kidding me?你是在开玩笑我吗？ This calculator is all about problems.这计算器是所有有关问题。 It was, in fact, the very first one I ever bought.这是，事实上，第一，我任何时候都买。 But I was disappointed, so I went in search of alternatives and ended up testing all the others.但令我感到失望，所以我去在搜索替代品和结束测试的所有其他人。 In this particular article, I am comparing BKGcalc with BizMathica because they are so similar.在这方面，特别是文章，我比较bkgcalc与bizmathica ，因为他们是如此的相似。 I think BizMathica is a lot better, but please keep in mind that this is a very personal choice.我认为bizmathica是好多了，但请记住，这是一个非常个人的选择。 You should certainly try them all before you make your final choice.您当然应该尝试，他们所有在您最后的选择。 All of them have free trial periods and that’s great.所有这些都免费试用期，并认为的伟大。

Pros: It is powerful and you might actually like not having an automatic num lock mode and typing everything on your own. 利弊：这是强大的和你实际上可能会不一样，有一个自动的Num Lock模式和打字都在您自己。

Cons: I don’t know about you, but I loathed not having automatic num lock mode. 意见：我不知道你，但我loathed没有自动的Num Lock模式。 Besides, I don’t think BKGcalc has as many functions as BizMathica or the HP emulators.此外，我不认为bkgcalc已作为许多职能bizmathica或惠普的模拟器。

But remember I am applying one single comparison method for this roundup of calculators:但请记住，我申请一个单一的比较方法，这综述：计算器：

Look and feel: 外观和感觉：	6六	(look is just OK, feel not so much) （看看是刚刚确定，觉得没有这么多）
Ease of use: 易于使用：	4	(I really really hate the lack of automatic num lock mode and the conversion feature is not great either) （我真的真的痛恨缺乏自动的Num Lock模式和转换的功能没有很大的要么）
Math functions: 数学函数：	6六	(not as many as the other calculators reviewed so far) （而不是许多人视为其他计算器审查至今）
Data display: 数据显示：	10 10月	(full expressions and ticker tape) （充分的表达和股票录音带）
Measurement conversion: 度量换算：	6六	(it’s there, but lacks useability and there are not that many measurement units) （它的存在，但缺乏useability有没有那么多的测量单位）
Average: 平均：	(6+4+6+10+6=32) / 5 = 6.4 （ 6 4 6 10 6 = 32 ） / 5 = 6.4
