Anyone have experience with calculators malfunctioning or miscalculating?

>>8502335
you typed something in wrong.

Your inputs were off.

>>8502339
>>8502340
No. I looked at my work over and over. This isn't the first time it has done this even in shorter problems. It only happens during things that require division. Calcs in the right mode and everything...

>>8502350
then the next problem you need to figure out is the order of operation in which the calculator calculates.

that's where 99.999999% of problems students have with calculations stem from.

I doubt your calculator calculates incorrectly.

>>8502368
Nope. No order of operations required for this. I literally followed an example step by step but used my numbers.

Post exactly what you entered into the calculator and what the result was.

have you no yardstick?

>>8502335
It is literally impossible for a calculator to be wrong. Literally. its hardware. The flow of electricity does not lie. Since you didnt type your inputs Im pretty sure you did something wrong.
Alternatively you could have been using a function that is calculated by a taylors series.

>>8502428
I just did the same exact problem with different numbers step by step using math way exactly as I would my calculator. Guess what? Fuckin right.

>>8502439
So Im just going to say again, its literally impossible for the calculator to be wrong. You did something stupid and probably laughably so. Without you saying what the input is its pretty clear.
Youre like some child complaining about rounding errors in a calculator when you were supposed to use fractions.

check radians or degrees

>>8502395
I deleted all of my memory because I thought they may have something to do with it and it may work properly now for all I know.

>>8502446
Bro you inputted something wrong. We all do it. Get over it.

>>8502445
In this instance, I required degree mode.

>>8502449
I'm "over" it but I'm still convinced there is something wrong that was not human error.
/thread

possibly, depends on calculator model.
may handle floats incorrectly and outputs a bad number. Check precision to see where it goes wrong. Integer usage causes truncation error so your program might be at fault here. Post the problem

>>8502475
also run each step individually to see where it deviates

>>8502443
this is bait

>>8502479
>I have no idea what calculators are
Go pick up a book on circuits. Its entry level stuff and it makes you seem really dumb.

>>8502463
>that was not human error.
Kek this is exactly why theres the basic rule that the computer didnt do something wrong, you did. idiots like you cant find your mistake.

>>8502491
please explain the zilog z80 CPU on the ti-84 and constituent firmware upgrades without digital circuit design

>>8502573
Every calculator uses the basic circuits for addition multiplication etc. Firmware has nothing to do with that. You can literally program a basic calculator with sticks and stones. Firmware deals with completely different scenarios.

>>8502463
so you want to find any excuse to protect your fucking ego, despite all evidence pointing towards something you did wrong.

I hate people like you.

this reminds me of all the people in my undergrad arguing with the prof that online tests had the wrong answers or malfunctioned and that they were right all along

You autists he probably has his settings fucked up. Check to see if your calculator is ser to degrees or radians. Assuming you are using the TI-84+ then click the mode button

>>8502830
You mean he did something wrong.

>>8502428
tell that to floating point arithmetic

>>8504085
floats are accurate to around the digits the calculator shows.
