I got at http://digital.ni.com/public.nsf/allkb/9D0878A2A596A3DE86256C29007A6B4A that LabView uses the Wichmann and Hill random number generator.
I would like to know if National Instruments is planning to improve it, so many years later the same authors mentioned that it may be inadecuated. This article can be downloaded from the web page of the National Physical Lab of UK: http://resource.npl.co.uk/docs/science_technology/scientific_computing/ssfm/documents/wh_rng_version.... The URL of the complete list of related documents is: http://www.npl.co.uk/mathematics-scientific-computing/software-support-for-metrology/publications/
Thank you very much!
(I have LabVIEW version 8.0)
