Why does .NET use banker's rounding as default?

Here is a sample code

decimal num1=390, num2=60, result;
result=num1/num2; // here I get 6.5
result=Math.Round(result,0);

the final value of result should be 7 but, I am getting 6. Why such a behavior?

Answer 1

Check third parameter MidpointRounding.

By default used MidpointRounding.ToEven, so

Math.Round(result,0); // 6.0 
//or
Math.Round(result,0, MidpointRounding.ToEven); // 6.0 

//But:
Math.Round(result,0, MidpointRounding.AwayFromZero); // 7.0
