vb double too small

I have a the following code

    Dim tmpStr$
    Dim tmpnumber$
    Dim tmpExponent$
    Dim tmpNewVal As Double

tmpnumber = 9.399999
tmpExponent= 11

tmpNewVal = CDbl(tmpnumber) * (10 ^ (CDbl(tmpExponent) * -1))
formatResultsPlus = FormatNumber((tmpNewVal * 1000), 3) & " mA"

When I use these values, formatResultsPlus = 0.00, when it should be a number.

I think the double is too small, please help.

The result is

0,000000094000 mA

-You can't print the result with only 2 decimal places.

formatResultsPlus = FormatNumber((tmpNewVal * 1000), 3) & " mA"

formatResultsPlus = FormatNumber((tmpNewVal * 1000), 9) & " mA"
