In C#, I’d like to round a double value to two decimal places. How can I achieve this?

double inputValue = 48.485;

after round up

inputValue = 48.49;

This works:

inputValue = Math.Round(inputValue, 2);

Math.Round(inputValue, 2, MidpointRounding.AwayFromZero)

ToString with an argument is another simple method. Example:

float d = 54.9700F;    
string s = d.ToString("N2");

You should use

inputvalue=Math.Round(inputValue, 2, MidpointRounding.AwayFromZero)



Essentially, the function above will round your input value to 2 (or whatever number you provide) decimal places. When a number is midway between two others, it is rounded to the next number that is away from zero with MidpointRounding.AwayFromZero. You also have the option of rounding to the nearest even number.
