C# - Rounding Down to Nearest Integer

Just try this..

 int interval = Convert.ToInt32(Math.Floor(different/increment));

Use the static Math class:

int interval = (int)Math.Floor(difference/increment);

Math.Floor() will round down to the nearest integer.

You can also just simply cast the result to int. This will truncate the number.

int interval = (int)(difference / increment);
