How to have a custom rounding function?

Basically, I need FormatNumber to behave slightly differently. Of course, we can write our own MyFormatNumber, but basically, it should return the following:

59.080 returns 59.08
59.081 returns 59.08
59.082 returns 59.08
59.083 returns 59.08
59.084 returns 59.09 ←
59.085 returns 59.09
59.086 returns 59.09
59.087 returns 59.09
59.088 returns 59.09
59.089 returns 59.09

As you can see, the only difference is when the 3rd decimal place is a 4, then I would like to round up. That is, when the input's third decimal place is 4 or greater, then do a round up, otherwise round down.

How can we do such a function in Classic ASP?

A custom rounding function could be implemented like this:

Function CustomRound(n)
  If n * 1000 Mod 10 < 4 Then
    CustomRound = Int(n * 100) / 100
  Else
    CustomRound = (Int(n * 100) + 1) / 100
  End If
End Function
