c# Divide operation Not working

post your full code

 

what is sw? convert it to double first

how would I do this with the elapsed time below to get the decimal

 

decimal test = (sw.ElapsedMilliseconds / 1000);  

that's because 2456 and 1000 being integer numbers, C# compiler considers them int variable hence you don't get any value after decimal point.

 

string test = (2456d / 1000d).ToString();

 

here you need to explicitly specify the compiler to consider your values as double.
