QUESTION
I am working on a small calculator application with Vue 3 and some custom CSS.
As far as I can tell, it works fine, with the exception of displaying long numbers as results.

QUESTION
I am new to android development. I was trying to implement a simple calculator using Kotlin. All the functionalities are working as expected except when I just input my first operand and operator but don't give my second operand and press equal instead it crashes.
Apparently what I got form the error is it's trying to execute "inputValue = binding.tvInput.text.toString()" but failing because their's no value in tvInput.
I think I have written an if statement in onEquals function to handle this, but it isn't working.
here's the code for your reference:

QUESTION
I am trying to teach myself Python Kivy and I have been working with this calculator program. I want to make the text for exponent different than what it being processed. It is normally ** but I want it to show ^ on the button. How do I get it show one thing and put in a different thing in the entry.text += self.text part. The other way I was thinking was trying to use a decorator, but I am not sure how to do that for an operator like that.
Any ideas?

ANSWER
Answered 2020-Feb-06 at 11:52As I understand you have tried checking whether the value of text field b is null. Have you tried to check whether b.text.isEmpty or isNotEmpty.
QUESTION
I sort of just wanted to have my code reviewed for logical purposes. I think it works out the way I expect it to but I'd like to double check with peers who are more versed in C#.
So here I am testing a console application which validates user input. I am using StringReader to simulate the user response. So I entered in 5 as my response and if my response is not a valid float then I should receive an error.
I tested this against a non-float value and my for loop caused me to enter a insufficient memory exception which makes sense. But for some reason in my test, I feel like I'm writing to my Input1() function and just validating that my input was indeed the value that i simulated? Or is my test actually validating that the return value of Input1() is actually num1 in the form of a float - thus passing my validation?
Sorry if this is overkill and not making sense.

QUESTION
Trying to get my unit test to run but after clicking "run tests", I just get "NUnit3TestExecutor converted 1 of 1 NUnit test cases" in my output. The test tries to run but just ends up loading forever till I have to manually cancel the process. Any idea what could be causing this?
...ANSWER
Answered 2020-Jan-03 at 02:43Based on your use of Console.SetOut I'm assuming you are testing a console program. I'm also assuming that it waits for input from the user.
Unfortunately, it is not getting any input from your code, so it hangs.
Testing a console app by driving it's input and output is possible but complicated. You would usually need to launch it in a separate process, monitor the standard and error outputs and drive the input. Most people do not test this way - at least not those experienced with unit testing.
A better approach is to test the backend that does your calculations.
There's one other complication I should mention... NUnit itself takes control of console output. For that reason, your test would need to save the current output setting and restore it before exiting - otherwise, NUnit's continued processing will be broken.
