Answer by Vincent Rithner for How to round to nearest even integer?

@Markyour snippet don't match Excel calculations.In Excel, try the following values:

• 210.61 -> 212

• 2.98 -> 4

• -2,98 -> -4

  with you code:

• 210.61 -> 210

• 2.98 -> 2

• -2,98 -> -4

I modified the code and it's working now:

public static double round_up_to_even(double number_to_round){    var converted_to_int = Convert.ToDouble(number_to_round);    if (converted_to_int %2 == 0) return Math.Round(converted_to_int, 0);    var difference = (converted_to_int + 1) - number_to_round;    if (difference <= 0.5) return Math.Round(converted_to_int + 1, 0);    var vOffset=converted_to_int < 0 ? -1 : 1;    return Math.Round(converted_to_int + vOffset, 0);}
