[Gambas-user] Octal to Integer Conversion

[T Lee Davidson]

While we're waiting for the Octal number representation issue to be resolved, I've coded up a little function that will convert
an octal number, represented as a string, to its correct integer representation.

[code]
Function OctStrToInt(Value As String, Optional Pow As Integer = 0) As Integer

  Dim char As String

  If Len(Value) = 1 Then
    char = Value
    Value = ""
  Else
    char = Right(Value, 1)
    Value = Left(Value, -1)
  Endif

  If char < "0" Or "7" < char Then Error.Raise("Invalid octal character '" & char & "'")

  If Value Then
    Return CInt(char) * 8 ^ Pow + OctStrToInt(Value, Pow + 1)
  Else
    Return CInt(char) * 8 ^ Pow
  Endif

End
[/code]

Use it like:
OctInt = OctStrToInt("644") ' yields 420
