    Come leggere un decimale

    Sto impazzendo,
    ho un dato con decimale su db mysql:
    In pratica rsq.fields("Qtap") sul db è 1.00.
    pertanto volevo prendere il numero intero cioè 1, quindi ho fatto:
    codice:
    byes = rsq.fields("Qtap")
    pozea = Instr(byes, ".")
    if pozea > 2 then
       QtaTAPA = Left(byes, pozea - 1)
    else
       QtaTAPA = byes
    end if
    Qta = QtaTAPA
    Ma QtaTAPA mi scrive sempre 1.00, ma come mai???
    AIUTOOOOO

    dal manuale vbscript
    codice:
    Description 
    Returns an expression formatted as a number.
    Syntax
    FormatNumber(Expression [,NumDigitsAfterDecimal [,IncludeLeadingDigit [,UseParensForNegativeNumbers [,GroupDigits]]]]) The FormatNumber function syntax has these parts:
    Part Description
    Expression Required. Expression to be formatted.
    NumDigitsAfterDecimal Optional. Numeric value indicating how many places to the right of the decimal are displayed. Default value is -1, which indicates that the computer's regional settings are used.
    IncludeLeadingDigit Optional. Tristate constant that indicates whether or not a leading zero is displayed for fractional values. See Settings section for values.
    UseParensForNegativeNumbers Optional. Tristate constant that indicates whether or not to place negative values within parentheses. See Settings section for values.
    GroupDigits Optional. Tristate constant that indicates whether or not numbers are grouped using the group delimiter specified in the control panel. See Settings section for values.
    Settings
    The IncludeLeadingDigit, UseParensForNegativeNumbers, and GroupDigits arguments have the following settings:
    Constant Value Description
    TristateTrue -1 True
    TristateFalse 0 False
    TristateUseDefault -2 Use the setting from the computer's regional settings.
    Remarks
    When one or more of the optional arguments are omitted, the values for omitted arguments are provided by the computer's regional settings.

    Note All settings information comes from the Regional Settings Number tab.

    The following example uses the FormatNumber function to format a number to have four decimal places:
    Function FormatNumberDemo Dim MyAngle, MySecant, MyNumber MyAngle = 1.3 ' Define angle in radians. MySecant = 1 / Cos(MyAngle) ' Calculate secant. FormatNumberDemo = FormatNumber(MySecant,4) ' Format MySecant to four decimal places. End Function
