La funzione "gst_util_guint64_to_gdouble()" del API di GStreamer, usata in Gambas, converte un valore di tipo Long in un valore di tipo Float (il double del C).

Mostriamo un esempio:

Library "libgstreamer-1.0:0.2410.0"

' gdouble gst_util_guint64_to_gdouble (guint64 value)
' Convert value to a gdouble.
Private Extern gst_util_guint64_to_gdouble(value As Long) As Float


Public Sub Main()

  Dim l As Long
  Dim f As Float
 
  l = 44444
  
  f = gst_util_guint64_to_gdouble(l)
   
  Print f
 
End
