Hello,

I am pulling a "money" field from an SQL Database. When I add it to a listbox I use "GetDecimal()". The listbox results in data with 4 decimal places. I need to change this to 2 decimal places. How can I do this

Hi,

Convert it to string and get the substring what ever u want and convert the result back to decimal.

If u can give me the decimal (source value) and target decimal value, i'll also try.

Thanx,

There's the: System.Math.Round

Kane-

double d = 17.4501;
d = Math.Round(d, 2);

Edit: er.. Lotus seemed to beat me to it :)

Hi Kane,

it's decimal not double.

Thanx,

The library call is still the same :)

Decimal d = 17.3501m;
d = Math.Round(d, 2);

Remember for monetary calculations you always want to use decimal. Double is accurate to only 15 positions. Check out this post Double Subtraction extra value unexpected. Also, you may not have this problem, but foreign databases sometimes truncate instead of round financial calculations and you will begin to find your values off so slightly.

You can use NumberFormatInfo and set the number of decimal places:
NumberFormatInfo nfo = new NumberFormatInfo();
nfo.NumberDecimalDigits = 2;

so when you need to printout decimal number with two digits use this method:

decimalVariable.ToString("N", nfo);
