Great workaround!! I created a snippets page on the wiki some time ago, you will find a link on the main page.

Almost forgot... Some weeks(?) ago I noticed that people tend have problems with floating point precision (problem with all general purpose languages). So, I'll share my quick & dirty solution. Short but useful code if you need very precise numbers for math, but speed is not crucial. I personally use it for prototyping. This is for class (name it BcClass): Private hPro As Process Public Function _call(sFunc As String) As String Dim ss As String Print #hPro, sFunc Input #hPro, ss Return ss End Public Sub _new(Optional iPrecision As Integer = 100) hPro = Exec ["env", "BC_LINE_LENGTH=0", "bc"] For Read Write Print #hPro, "scale=" & CStr(iPrecision) End Public Sub Stop() hPro.Close() End This is how you use it: Dim Calculate As New BcClass(8) Print Calculate("1+2/7^2.4") 1.04081632 And when all calculations are done, end your code with "Calculate.Stop()". BTW. Is there some place for code snippets?
