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?

[–] tpihkal@lemmy.world 107 points 3 days ago (2 children)

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

Calculators are similar to a Dark Souls game.

If that were true then mashing buttons on your calculator would prevent any inputs from being processed for a few seconds.

Fromsoft believes in punishing button-mashers.

[–] Xanis@lemmy.world 26 points 3 days ago

Unless it's Dark Souls 2 wherein you mash a couple buttons after being knocked down or rolling and manage to queue up your binoculars perfectly. This, in turn, allows you to get a really splendid look at your enemy's grimacing face as he shoves a rather vicious and often seriously pointy metal object up your ass. All the while you're frantically trying to roll away and accidentally toss back a flask. This manages to save you from an untimely demise until you notice that you backed up a little too much and that dude waiting to ambush took one last drag from his cigarette, flicked it away, and proceeded to club your head like he was Babe Ruth after a particularly hearty breakfast.

Then on the way back to your souls some asshole named "Forsworn" gets in your way. God only knows what his problem is.

And in my mind "CE" is "Clear everything". I'm keeping OP's method

doesn't everyone know it stands for Celery Endives?

Should be replaced with a backspace icon and a trash can icon

[–] Moobythegoldensock@lemm.ee 63 points 3 days ago (2 children)

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.)

[–] Rhaedas@fedia.io 28 points 3 days ago (3 children)

Why didn't they just make one Clear and make another Backspace? The concept of erasing the last character had been in typewriters for a while by then, and this is far more obvious. Maybe erasing a single digit in earlier software/hardware was much harder than just clearing it all?

That's why it never worked for me. I assumed CE was Clear Everything.

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

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.

[–] KillingTimeItself@lemmy.dbzer0.com 21 points 3 days ago (1 children)

ah yes, wait until you find out about the qwerty keyboard. Or better yet, the fucking ABCDE layout for some godforsaken reason.

[–] T156@lemmy.world 33 points 3 days ago (1 children)

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.

[–] sushibowl@feddit.nl 6 points 2 days ago (3 children)

I think people exaggerate how bad QWERTY is. Studies have not consistently found an advantage for one keyboard layout over another, and some studies even show that typists can reach equivalent speeds even with randomised layouts. This suggests that experience and practice with a particular layout is far more important to typing speed than the particular placement of letters. Which is a good argument for keeping qwerty around.

(reducing the risk of mechanical typewriters jamming by not having two hammers next to each other be pressed at the same time),

This story is quite common but there is little evidence that it's actually true. The designer of qwerty actually made a late adjustment to move R next to E (swapping it with period), even though ER is the second most common letter combination in English.

there are two big arguments for a denser layout, notably you move your hands less, which means you can type faster, statistically speaking. It makes it easier. Generally you see typing speed track roughly with this over time.

And since you move your hands less, it's ergonomically better for typing, so you get less strain, you have better ergonomics in general, you can type longer, and even faster since there is less strain.

Different layouts optimize for different things, some optimize for efficient roll combinations, some optimize for switching between hands as optimally as possible. Some don't really do any of that (qwerty) which also have a significant impact on typing.

[–] piccolo@sh.itjust.works 5 points 2 days ago

Even the keyboard design itself can effect typing results. Like typing on a really good mechanical keyboard is more comfortable than a shitty chiclet keyboard.

[–] Swedneck@discuss.tchncs.de 1 points 1 day ago

Layout isn't really about speed, it's about comfort
I've been using modified colemak for like a year now and good lord it's so much nicer to use: you just place your fingers on "arst neio" in my case and then 80% of the keys you actually use on a regular basis are within a tiny finger movement to reach.
And then there's the fact that you're almost always using a different finger for the next letter, suuuper smooth typing experience.

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.

[–] figjam@midwest.social 10 points 3 days ago (1 children)

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.

[–] piccolo@sh.itjust.works 4 points 2 days ago

The solution is mandate standards to be adhere too and any contractors must have no patents so any manufacturer can be used.

[–] red_pigeon@lemm.ee 12 points 3 days ago (2 children)

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

[–] merc@sh.itjust.works 13 points 3 days ago (1 children)

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".

[–] Swedneck@discuss.tchncs.de 1 points 1 day ago

basically: calculators should be like old digital typewriters, ideally with an easy to use scripting language built in.

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.

Press both simultaneously, while twisting the joystick in a "C" motion, to launch a fireball.

There sure is a lot of overlap with people criticizing the technical interface of a calculator and nerds, wonder why that is? Oh well glad I’m not one of those nerds, now back to the clear button being so obtuse.

It's solar powered so I just wait for night time to clear it then do the next problem in the morning

Mate, you can just put your finger over the solar panel until it slowly gets strangled

Now we know the C stands for Cum and CE for Cum Edging

They should have gone with Clear Line instead of Clear Entry, because CE could also be Clear Everything… which is what clear does.

The calculator on my phone has an "AC" button, further confusing the situation.

[–] subterfuge@lemmy.world 59 points 3 days ago (1 children)

The AC button cools the air around you.
