you can use a variable declared as Decimal and assigned value is 0 then add it to your variable you want to set precise

dennis, #.00 is correct.
515.4445 when rounded to 2 decimal places is 515.44.
This is because the number in the third decimal place (4) is less than 5.
515.4454 would round to 515.45, because in this case the 3rd decimal place (5) >= 5

double valuetoround = 515.435;

roundvalue = valuetoround.ToString(”#.00″);
this method seem to be flawed also just try :

515.4445 it will round to 515.44 instead of 515.45

use ToString Method as follow

double valuetoround = 515.435;

roundvalue = valuetoround.ToString(”#.00″);

You will get your required ans. 515.44 instead of 515.43

I’m having a hard time with Math.Round. Any idea why:

Math.Round(515.435, 2, MidpointRounding.AwayFromZero)

returns 515.43 in VB.NET 2008? I really, really need it to return 515.44.
