Round Off decimal values in C#

Question

how do i round off decimal values ?
Example :

decimal Value = " 19500.98"

i need to display this value to textbox with rounded off like " 19501 "

if decimal value = " 19500.43"

then

value = " 19500 "

Solution 1

Look at Math.Round(decimal) or the overload which takes a MidpointRounding argument.

Of course, you'll need to parse and format the value to get it from/to text. If this is input entered by the user, you should probably use decimal.TryParse, using the return value to determine whether or not the input was valid.

string text = "19500.55";
decimal value;
if (decimal.TryParse(text, out value))
{
    value = Math.Round(value);
    text = value.ToString();
    // Do something with the new text value
}
else
{
    // Tell the user their input is invalid
}

Solution 2

Math.Round( value, 0 )

Solution 3

Try this...

 var someValue=123123.234324243m;
 var strValue=someValue.ToString("#");

Ceiling rounds it up. 19500.43 will become 19501, and not 19500 like the OP intended.

yes so if you want to round off amount if it is greater that 0.5 then u can use Math.Round(Value, MidpointRounding.AwayFromZero);
