How to round off decimal to two decimal places in C# ?

There are 3 ways to round off decimal to two decimal places :

1. Use ToString()

 double  d = 2.445;

 d.ToString("0.00")



Output : 2.45



2. Use Math.Round



double d = 2.445;



Math.Round(d, 2)



Output : 2.44



3. Create a Custom logic method like below :



N = 2.445 I want to show "2.45" only.



Step a. N*100 + 0.5 = 245

Step b. Divide System.Math.Floor(245) by 100

Step c. The result will be 2.45
