[Gambas-user] Check on entered number having more than 6 digits not working

[John Rose]

I'm trying to validate an entered Latitude value as having a maximum of
6 digits after the decimal point. Sometimes it doesn't work. In the case
below, it is 48.590278. This should be valid, but the
'Message.Info("More than 6 decimal digits - try again")' line is being
executed. As you can see from the Print statements, the check should be
OK. Am I missing something really obvious?

Public Sub ValueBoxLatitude_LostFocus()
  Dim latitude As Float
  Dim f As Float
  Dim g As Float
  If IsNull(Last.Value) Then Return
  latitude = Last.Value
  If latitude < -90 Or latitude > 90 Then
    Message.Info("Must be between -90 and +90 - try again")
    Last.SetFocus()
    Stop Event 
  End If
  f = latitude * 1000000
  g = CFloat(CInt(f))
  Print "f=" & f
  Print "g=" & g
  If f <> g Then
    Message.Info("More than 6 decimal digits - try again")
    Last.SetFocus()
    Stop Event
  End If

f=48590278
g=48590278
