IsNumeric("6d6") = True ????
Code:
If IsNumeric("6d6") Then
MsgBox ("IsNumeric")
Else
MsgBox ("Not IsNumeric")
End If
Why is the string "6d6" numeric? Could someone please explain?

because the character "e" inside number is meaningfull and means:
multiply the number before that character in 10 power the number after that character. and for some reason which I still don't know, "d" has the same meaning exactly. thus, 6e1 is 6*10=60, 6e2 is 6*(10^2)=6*100=600 etc... pretty unique situation, how did you stumble upon it? anyhow, you can "solve" this by manually checking the string for "d" or "e" characters.

I was doing tests with my component and I randomly typed 6d6 just to make sure all validations were working fine and I had this strange surprise...
At least it wasn't the client who stumbled upon this
