i         


        

Answer 1

Use Math.Round

value = Math.Round(48.485, 2);

Answer 2

Use an interpolated string, this generates a rounded up string:

var strlen = 6;
$"{48.485:F2}"

Output

"48.49"

Answer 3

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

Answer 4

I think all these answers are missing the question. The problem was to "Round UP", not just "Round". It is my understanding that Round Up means that ANY fractional value about a whole digit rounds up to the next WHOLE digit. ie: 48.0000000 = 48 but 25.00001 = 26. Is this not the definition of rounding up? (or have my past 60 years in accounting been misplaced?

Answer 5

Another easy way is to use ToString with a parameter. Example:

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

Result:

54.97

Answer 6

This works:

inputValue = Math.Round(inputValue, 2);
