C# visual studio, visual calculator

[Flanelman]

I'm currently writing a code to run a calculator, but im having some trouble.

1)

I have 2 input text boxes and one output text box:

//Input

            int one = Convert.ToInt16(onetext.Text);

            int two = Convert.ToInt16(twotext.Text);

            

//Output
           int three = Convert.ToInt16(threetext.Text);

and when i try to Mod the two numbers like this:
int sum = one % two;

i get an error with the third text box, but not on any other equation type, divide, minus, add, multiply etc.

 

-----------------------------

2)

      when i divide the number, say i divide 10/3, it gives me 3, rather than the actual answer including decimal, does anyone know how to fix this?


this is all done in visual studio as a windows visual application if that helps

thanks in advance.

I would suggest using

 

int one = int.Parse(oneText.Text);

etc etc etc...

 

But go on what is the question @Flanelman?

Okay, think I replied before you were finished.

 

Not sure about your modulo '%' problem but for the decimal point things. Int can only hold whole numbers, use something like double or float and you'll get your decimal point.

haha yeah sorry ia ccidentaly submitted when i was mid typing the mod one im not sure why it isn't working, but the divide one gives me an error if i change it to double. i changed the code to this:

 

            int one = Convert.ToInt16(onetext.Text);

            int two = Convert.ToInt16(twotext.Text);

            double three = Convert.ToDouble(threetext.Text);      **gives error here just like before

 

            double sum = one / two;

            threetext.Text = Convert.ToString(sum);

 

any ideas what ive done wrong?

thanks for your help btw

 try casting to double.

 

double sum = double(one)/double(two)

or

double sum = double(one/two)

 

and if memory serves, you don't need to convert int to string you could just do it directly like

threetext.Text = sum;

 

hope this helps

 

Edit: Still don't get why your mod code won't work... should be working fine though...

Additionally, could you provide the error message?

For your second issue, instead of converting the textbox into an integer, convert it to decimal.

 int one = Convert.ToDecimal(onetext.Text);

And do that for the other integers as well and then pass that value back into the calculators textbox.

got it all working, i deleted the line 

 

Additionally, could you provide the error message?

i was able to fix both errors by removing this from the code in both parts.

as well as changing one of the two remaining text boxes to double.. strange but got it all workign now i thought i'd post to et you know why the mod part wasnt workign haha

 

thanks for your help

int three = Convert.ToInt16(threetext.Text);
