  • This answer shows how to round to 2 decimal places, change the number from 2 to 3:https://stackoverflow.com/questions/257005/how-do-you-round-a-number-to-two-decimal-places-in-c – Sparrow Nov 22 '17 at 23:05
  • What results do you expect for these sample inputs - `0.1111` `0.1115` `0.1125` `-0.1111` `-0.1115` `-0.1125`? – mjwills Nov 23 '17 at 00:41

You can use:

Math.Round(n, 3);

To always round up, you can use:

Math.Ceiling(n * 1000) / 1000;

According to this link https://msdn.microsoft.com/en-us/library/6be1edhb(v=vs.110).aspx

You'll need to do something like Decimal.Round(n, 3);

However your initial approximation is not accurate
