When using Math.Round You have two choices for rounding x.5:

Banker's round / Round to even. Avoids biases, by sometimes rounding up(1.5=>2) and sometimes rounding down(0.5=>0), used by default if you don't specify the parameter.

Int32 i=Math.Round(d, MidpointRounding.ToEven);

The rounding you learn at school, where it always rounds towards infinity (0.5=>1, -0.5=>-1)

Int32 i=Math.Round(d, MidpointRounding.AwayFromZero);

Use Math.Round first.

Try something like :

Double d = 1899.99;
Int32 i = Math.Round(d);
String retval = i.ToString(CultureInfo.InvariantCulture);
