c# - Why textBox in WinForms cant display double? - 


using system; using system.collections.generic; using system.componentmodel; using system.data; using system.drawing; using system.linq; using system.text; using system.threading.tasks; using system.windows.forms;  namespace p2_7_24_2016_ed_app {     public partial class form1 : form     {         int win;         int loss;         int wincounter;         int losscounter;         public form1()         {             initializecomponent();         }          private void buttonwin_click(object sender, eventargs e)         {             this.textboxwin.text = "";             ++win;             ++wincounter;             this.textboxwin.text = win.tostring();         }          private void buttonloss_click(object sender, eventargs e)         {             this.textboxloss.text = "";             ++loss;             ++losscounter;             this.textboxloss.text = loss.tostring();         }          private void buttonrate_click(object sender, eventargs e)         {             textbox1.text = "";             double result = wincounter / (wincounter + losscounter);             textbox1.text = result.tostring();         }     } }

this code in windows form application, short i'm not going explain everything. problem in end textbox1.text = result.tostring(); showing "0", should numbers. when win wincounter 1, , losscounter 1 should insert 1/(1+1) = 0.5 says "0". tried knew please give me tip.

this integer arithmetic:

(wincounter/(wincounter+losscounter))

the result not going expect.

cast either wincounter or (wincounter+losscounter) floating point type (float, double or decimal depending on speed/accuracy need) before doing division:

 (wincounter/(decimal)(wincounter+losscounter))

or

 ((double)wincounter/(wincounter+losscounter))

and you'll result expect.
