I want to round the decimal value like this
if 5.50 => 5
if 5.51 => 6 ..
I want if the decimal value after point getter than .50 then the value increment by 1.
I used Math.Round() function, but it's round after .49 decimal value..

Use a custom rounding system:

public int Round(double value)
{
    double decimalpoints = Math.Abs(value - Math.Floor(value));
    if (decimalpoints > 0.5)
        return (int)Math.Round(value);
    else
        return (int)Math.Floor(value);
}

Hope this helps. Smile | :)

public int myRound(double val)
{
    return (int)Math.Floor(val + .49);
}
I don't like "magic numbers" so you might want to define a const double and swap it for the 0.49

Solution 1

basic and simple way , you can convert decimal (5.50) to int (5) and you can check for 5.50-5 greater or lower than .50 if bigger then apply your algorithim..but i dont know any other function does that automaticly.
