The cast to int acts like a Floor() method for positive values. For negative values, it's like Ceil().

Anyway, there's no point in rounding its return value.

Use Math.Round[^] or Math.Ceiling[^] or Math.Floor[^] method.

Example:

C#

Math.Round(4.4); //Returns 4.0.
Math.Round(4.5); //Returns 4.0.
Math.Round(4.6); //Returns 5.0.

You can do it in this way to:

C#

double x = 1234.7;
int a;
// Cast double to int.
a = (int)x;  //Result: 1234
