Convert float to gchar *

["Laurent Houdusse" <l houdusse free fr>]

Hi!

I need to convert float in gchar*
is there a function in glib?

see my code:
void RefreshFramePerSecond(void)
{
	float fNbFps;
	fNbFps = oDw3D.GetNbFps();
	gtk_window_set_title(GTK_WINDOW(oWindow),fNbFps);//error to convert float
to const char*
}

Thanks!
