Eval function decimal places
Richard Pitassy

Is it possible for the Calc field to return a result with the number of decimal places I choose?  Formatting the calc field does not do the trick?

It sure is. I added a text box (or you could use a combo box) called DecPlaces and set the Default Value to 0.
I then modified the code:

If Not IsNumeric(DecPlaces) Then DecPlaces = 0
If InStr(DecPlaces, ".") <> 0 Then DecPlaces = Int(DecPlaces)
Calc = FormatNumber(Eval(Calc), DecPlaces)

Can you say where you put this modified code the decimal places?

Works great.

In the DoCalc Sub Routine on the Calculator form.

Modify the line that is already there (Calc = Eval(Calc)) with the FormatNumber as above.
Add the 2 If statements above that line.

Gary:  It goes behind BtnEval (Equal button).  w.

Private Sub BtnEqual_Click()
On Error GoTo MyErr

    If IsNull(Calc) Then Exit Sub
    Calc = Replace(Calc, "'", "/")
    Calc = Replace(Calc, "x", "*")
    
     If Not IsNumeric(DecPlaces) Then DecPlaces = 0
     If InStr(DecPlaces, ".") <> 0 Then DecPlaces = Int(DecPlaces)
     Calc = FormatNumber(Eval(Calc), DecPlaces)
     Exit Sub
    
MyErr:
    Calc = "Error!"
    Calc.ForeColor = vbRed
    Beep
    Resume Next
    
End Sub
