c# - How do I round a decimal value to 2 decimal places (for output on a page)

I want to truncate the decimals like below

i.e.

• 2.22939393 -> 2.229
• 2.22977777 -> 2.229

Answer 1

You can use Math.Round:

decimal rounded = Math.Round(2.22939393, 3); //Returns 2.229

Or you can use ToString with the N3 numeric format.

string roundedNumber = number.ToString("N3");

EDIT: Since you don't want rounding, you can easily use Math.Truncate:

Math.Truncate(2.22977777 * 1000) / 1000; //Returns 2.229
