Re: Mersenne: Java/javascript anyone?
Yes, this can definitely be done in JavaScript that works in both IE and Netscape. I am willing to write the code, but I won't have time until about May 5th or so because I have exams and that type of stuff occupying my time for the next week.

George, I've come up with a dynamic javascript form for the purpose. It needs a little more work to be done. I'm converting the numerous 'if' statements into an array lookup, and making it calculate out more than just days... I should have it fixed up within two or three days I'll send it to you when it's finished to your opinion at that time!

Re: Mersenne: Java/javascript anyone?
That's correct in calculations. That's how I calculated my own time, independent of the computer. Since it said it was going at 1.75 seconds per iteration, and there were 9025267 iterations to go, I just multiplied 1.75 by 9025267, and rounded high (knowing I'd be stopping every now and then), and used my TI-85 to turn that into days. That just divides the number by 86400. So it said I had to take 182.8034222 More days till the end. Finally, considering that the whole thing started March 10th, I went to the calendar, and counted out 183 days. I think that you can calculate that, in Java. Anyway, my calculations said that I'd be done some time around September the eleventh. Of course, I wanted to know when, so I took 182.8034222, and took the whole think mod 1, giving the fraction .8034222, which I converted back to hours, by multiplying by 24, giving 19.2773. so, it would be 19 hours from when I started, that being the basis of my calculation. This I took mod 1, giving .2773 which I multiplied by 60, to give the number of minutes, giving 16.4 , so I knew there would be 16 minutes. This I also took mod 1, giving .4, which I multiplied by 60, giving 24 seconds from when I started. PS I also started learning Java a little bit ago, and I may be able to help, but not until summer.

Then divide by 86400, the number of seconds on a day, and get 2016000 / 86400 = 23.3 days. Now calculate CPU hours per day (homework) :-) Unless, of course, I'm even more tired than you are Selah!
