My Casio calculator says the result is : 0.999999999. Does this mean I can get them to replace the CPU? I know exactly what you mean, but Intel themselves say this is a bug and they will replace cpu's which exhibit these anomolies. The author of the test program has sent me email to suggest that he wasnt happy himself with the version of the test program here and he has emailed me a newer version... I'll post it (or not) if people want...
