  CE is Clear Entry. If you want to hit 2 x 4, but accidentally press 2 x 44, you can press the CE button before pressing = to clear the 44 but not the “2 x” part.

  C will clear all of it so you can start over at the beginning.

  Pressing CE twice may or may not clear entries in reverse order, depending on you calculator model.

    So you’re saying mash both a bunch of times to be super sure?

      Calculators are similar to a Dark Souls game. You always restart from the beginning.

    Problem is on some calculators C is clear all and CE is clear entry, on some C is clear entry and AC is clear all, and some have a C/AC or CE/C button where it’s press once to clear entry and press twice to clear all.

    So it’s safest to mash unless you really know your calculator, because the industry can’t get its shit together, and that’s the sole reason it died (I’m assuming.)

      Thanks I was looking at the answer and thinking it didn’t fit my memory. i’m sure most of mine were ACs. TBF with things like VPAM coming in the late 90s, you did have backspace and all sorts of stuff like that.

      I still remember doing linear regression in a stats exam on i think a casio fx-115W something like that . Excellent calculator - but just no, it was time for some things to be on a real computer.

    You mean CE doesnt stand for “clear everything”? And here I thought more letters meant more clearing.

    But sometimes CE is “Clear Everything” and it works exactly the opposite way.

    source
  • rickyrigatoni@lemm.ee ⁨1⁩ ⁨month⁩ ago

    And it all depends on the calculator. The one right next to me only has a CE button and it acts as a C button. So not even the people making them know what they do sometimes.

    I discovered that hitting something like C, CE and 0 simultaneously for some reason worked as an instant power off for my school calculator. Do calculators have such hidden off-buttons? Because I have discovered other calculators with other combinations.

    • petrol_sniff_king@lemmy.blahaj.zone ⁨1⁩ ⁨month⁩ ago

      There’s actually a neat reason for this! The way that simple keys work, like those in a calculator, is by connecting a circuit and letting a small amount of voltage through. This is usually fine because the keypad is broken up into different rollover zones, which is how multi-key input works. But if you find and press keys that are all in the same zone, their voltages add up and can actually overwhelm the little cpu in there. Really old calculators were really easy to break because designers never thought users would need to press keys like division, multiplication, subtract, add, square and square root all at once, which as you can imagine, caused a massive power spike.

      Now, is any of this true? I have no idea dude, you’re calculator was probably fucking haunted or something. I’d have taken that thing to a seance with a ouija board immediately.

  Calculators just have a bad user interface in general. It’s pretty amazing that the UI was established in 1970 and was never changed after that.

    • T156@lemmy.world ⁨1⁩ ⁨month⁩ ago

      In defence of QWERTY, it did a decent job for what it was designed for (reducing the risk of mechanical typewriters jamming by not having two hammers next to each other be pressed at the same time), but really oughtn’t have lasted past the point where the risk of jamming was not longer there.

    Well, they’ve sold the same product for about the same price since 1970, so it makes sense. I have no idea how schools can require a specific device from a specific manufacturer. It’s just straight up market control by a public entity.

      Its to make sure that they don’t get a billion questions about what button to push next and not being able to complete homework because of button confusion. Does it still need to exist today? Probably no but good luck getting rid of a standard adopted by all manufacturers of textbooks.

    Curious to know why ? Basic functionality seems very obvious and friendly to me.

    • captain_aggravated@sh.itjust.works ⁨1⁩ ⁨month⁩ ago

      If there is any nuance beyond a 4-function calculator with a single clear button, any nuance or deviation from any kind of standard will not be clearly explained.

      There’s never a backspace key, only two “clear” buttons that have nuance between them and little to no description as to which does what.

    • merc@sh.itjust.works ⁨1⁩ ⁨month⁩ ago

      For one thing, just displaying the latest number isn’t useful if you’re doing anything complicated. For another, many calculations involve using the same number over again multiple times. Some calculators have a memory entry, but many don’t. There’s a “C/CE” but there isn’t a backspace, so if you get one digit wrong, you have to start that entry over (and hope you chose the right option among C/CE/AC/CA/etc. If you accidentally hit the wrong operation key (multiply, divide, plus, minus) AFAIK there’s no way to clear the operation. A lot of common math operations involves parenthesized expressions, but if you’re using a basic calculator you have to instead enter things in an unnatural order. It’s pretty common to end up in a situation where the calculator is displaying B and you want to do A/B but you can only easily do B/A. Fancy calculators have a 1/X button to fix this, but if not you’re out of luck. Same with having B and wanting to do A-B but only being able to do B-A. You can fix that by multiplying by -1, but again, it’s a UI issue that you can’t just say “hold onto that number for a second because I want to enter another number and then use it”.

    But it has been changed a lot?

    The most basic immediate execution four operation calculator might still look the same, but that’s because it’s a very simple thing and you can’t really get much wrong. For scientific calculators the UI has changed lots. As have the requirements. It used to be a specialist tool used to do thousands of calculations daily. RPN and stuff like that made sense for people who could easily get back weeks of training in just a few years of being slightly more efficient while working. Now we have the natural order delayed execution thing, because the calculators are mostly for students. Who need the UI to be as easy to grasp as possible, because they won’t ever have to do enough calculations to benefit from a faster but harder UI. That doesn’t mean any of those approaches to UI is better or worse. Some things require instructions and making everything idiot-proof shouldn’t ever be the ultimate goal (check out modern computing for why!).

      (check out modern computing for why!)

      Because when you need to do a process a thousand times, you program it in an actual computer. Then you just have a specific interface for just your process that makes everything simple.

      And the developer really only needs to understand the process for a couple months. Once it’s confirmed working correctly, you’re generally done with that piece of code.

    Let’s be honest, if you are doing serious math, you’ll have a graphing calculator to do way more stuff, and the controls are much more like a mini computer (with a backspace key, and being able to delete individual lines of history, or all of the history with menus)
