Description:
Digits to the right of the radix that are stored in the server are not found in the fld.Value.  Although the fld.NumericScale property does properly indicate the number of decimal digits. 
This problem is not seen in MyODBC 3.51.14

How to repeat:
SETUP:
mysql> CREATE TABLE ado_test (C1 INT PRIMARY KEY, C2 DECIMAL(10));
mysql> INSERT INTO ado_test VALUES (1, 101.25), (2, 202.49);

VB code:
Private Sub Test()
    On Error GoTo EH
    Dim strSQL, strConn As String
    Dim connection1 As ADODB.Connection
    Dim recset1 As ADODB.Recordset
    Dim fld As Field
    Set connection1 = New ADODB.Connection
    Set recset1 = New ADODB.Recordset

    strSQL = "SELECT * FROM ado_test"
    strConn = "DRIVER={MySQL Connector/ODBC v5};" & _
            "SERVER=localhost;DATABASE=ado" & _
            ";UID=root;PWD=mypass;OPTION=3;"

    'open connection
    connection1.ConnectionString = strConn
    connection1.CursorLocation = adUseServer
    connection1.Open

    recset1.Open strSQL, connection1, adOpenForwardOnly, _
                 adLockOptimistic, adCmdText
             
    recset1.MoveFirst
    While Not recset1.EOF
       For Each fld In recset1.Fields
           If fld.Type = adNumeric Then
               Debug.Print fld.Value
               Debug.Print fld.NumericScale
           End If
       Next
       recset1.MoveNext
    Wend
    Exit Sub

EH:
    Debug.Print Err.Description & " " & Err.Number & vbNewLine

End Sub

I messed up the table definition, should be...
mysql> CREATE TABLE ado_test (C1 INT PRIMARY KEY, C2 DECIMAL(10,2));
