There is a way to get the numbers to export with more than 2 decimal places
--save the table as a query
--create a calculated field for the number with more than 2 decimal places
for example
if you want 6 decimal places, in an empty field in the query type
A:Format([YourNumberField], "0,000000")
0 is for all numbers to the left of the decimal place holder
000000 is for 6 decimal places, change the number of zeros to suit

--export the query instead of the table
--unfortunately this method gives all the numbers exactly the number of
decimal places specified in the format
--if your number originally was 23.156 it would be exported as 23.156000

I didn't realise that Access 2003 always cut numbers to 2 decimal places
when exporting a table to .txt format.
That is not very useful.

There is a better way to do this.
You still need to save the table as a query.
Use a calculated field
In an empty column in the query type this:
B: IIf(Len([YourNumberField])>0,CStr([YourNumberField]),"")

--B is the new name for this calculated field ( you can give a different
name)
--converting the number to a text string saves the correct number of decimal
places for each number
--export the query

That would export the data as text, could round values (and do you
know which rounding algorithm?), etc. Perhaps better to work with the
raw data :)

Use a schema.ini file to specify data types or simply get the engine
to generate one for you e.g. ANSI-92 Query Mode syntax:

CREATE TABLE Test (
dec_col DECIMAL(10, 5) NOT NULL
)
;
INSERT INTO Test (dec_col) VALUES (12345.6789)
;
INSERT INTO Test (dec_col) VALUES (9876.54321)
;
SELECT dec_col
INTO [TEXT;Database=C:\;].NewFile#txt
FROM Test
;

The generated file named 'NewFile.txt' contains this data:

"dec_col"
12345.6789
9876.54321

The generated schema.ini file (but could have been created manually in
order to be different from the mdb's schema if desired) contains the
following information schema:

[NewFile.txt]
ColNameHeader=True
CharacterSet=1252
Format=CSVDelimited
Col1=dec_col Decimal Precision 10 Scale 5
