[Gambas-user] Feature request: Array.Frequency

[Patrik Karlsson]

Ok, so the module looks like this now, is Variant slower than other native
data types?

Export
Fast

Public Function Frequency(avValues As Variant[], vValue As Variant) As
Integer

  Dim i As Integer
  Dim iFrequency As Integer

  For i = 0 To avValues.Length - 1
    If avValues[i] = vValue Then
      Inc iFrequency
    Endif
  Next

  Return iFrequency

End
