Android Question How to Use Negative Numbers in a B4XPlusMinus

[bocker77]

The documentation for B4XFormatter is blank, https://www.b4x.com/android/help/b4xformatter.html, so I have nothing but an example from Erel to go by which I am not sure I understand it. Anyway I am wondering what the RemoveMinusSign does. It is not in his example.

Here is what I got but when I run it the number in the B4XPlusMinus range field is blank.

    pmInput2.Formatter.GetDefaultFormat.MaximumFractions = 0
    pmInput2.Formatter.GetDefaultFormat.MinimumFractions = 0
    pmInput2.Formatter.GetDefaultFormat.RemoveMinusSign = False
    Dim strLow As String = pmInput2.Formatter.Format(-80)
    Dim dLow As Double = strLow
    Dim strHi As String = pmInput2.Formatter.Format(-86)
    Dim dHi As Double = strHi
    pmInput2.SetNumericRange(dLow, dHi, 1)

Private Sub pmInput2_ValueChanged (Value As Object)
    strNewLon = pmInput2.Formatter.Format(Value)
End Sub

Thanks

On the basis that -86 is lower than -80, try switching the values.

Duh. Not too bright am I. Thanks Steve for seeing the obvious.

I am working with Decimal Degrees DDDs and I guess I just didn't think of that. But I should have. Thanks again.

Ha, we've all done it. when you are looking too hard, it get's to the stage where you can't see anything.

This is the last place to go when you search for information.

Just use the search engine: https://www.b4x.com/android/forum/pages/results/?query=b4xformatter
The first search result explains the library.

Okie dokie. I stumbled across a link to that documentation during a search when not finding anything under a library explanation. Thanks for the heads up.
