[SHIRA]

does anyoone know if there is a function that count the number of digit in a
number?

Maybe:
=len(a1)

You can use this formula. It counts the number of digits for the number in
cell A1. Note that it counts the number of digits entered, not the number of
digits displayed. for instance if the number is formatted to show 2 decimals
and the number 5 is enetered, the cell will show 5.00, but since only 1 digit
was entered the formula will return 1...

=IF(ISERROR(FIND(".",A1)), LEN(ABS(A1)), LEN(ABS(A1))-1)

also I assume you don't count the decimal as a digit, nor the negative sign.

this was simple

Maybe:
=len(a1)

You will have to be careful with that:

Sub test()

Dim d As Double

d = 100
MsgBox Len(d)

End Sub

May have to do:
MsgBox Len(CStr(d))
