No one is getting defensive here that I know of. No one is trying to justify a mistake either. No I not one of the developers. Hahaha I just a student on here learning basic maths. I wrote my first real program two weeks ago. It just do a average and SDV for 12 numbers. So I have a long way to go. It‘s lot easier to do it on a spread sheet, but this teach me the basics of how all that works.
Andre Massow is the developer of the calculator and he will fix the Gamma function when he have a mind to. Even though the Gamma function on this calculator does not work the calculator is still a good calculator. The cigar lighter in my uncles truck not work either that not mean the truck is a piece of defective junk. Well maybe it is but that not the reason why.
Someone else mention a couple of weeks ago the Gamma was not working and that was when I found out what a Gama function is. I search for it and find posts by Alan, Heureka and Bertie explaining what it is. I also read about it on other sites. I know more than before but I still have a long way to go before I understand how to use it.
Most of the questions on here are from middle and high school students and a few from college. There is only a few on here who do theoretical and advanced maths like Alan, Bertie, Heureka, Nauseated and Rom who not come on here much anymore. Melody and CPhill do some too, but they mostly spend their time teaching us which shoe goes on which foot and how to tie them after we put them on. That is a good thing because we never learn to read Shakespeare if we not learn our ABCs.
You talk about a FREE calculator that can do the factorial of 10^6 and give you all the digits. But you should know it’s not really free, you just not the one paying for it. Mr. Massow run his own servers and do all the technical work for the calculator and this forum to make it work. The only money he make is from the ads on the Calculator page. That probably not even pay for the electricity to run them. Germany have the highest electric rates in the world so it cost plenty.
I cant run the program you link to because I have a tablet and it not work on them. Anyway as for doing a factorial of a 1,000,000 I still think it will take a long time because it is millions and millions of digits long. Also I not know how you get the first 1000 digits without doing the whole thing. But there is a lot of things I don’t know.
If you know how to do that I would like to see it and I bet many others on here would like to know too. So make a post and explain it. Believe me there are a lot of members on here who will read it. If it’s a big pile of BS Nauseated might point it out and make a monkey out of you. The others will be more polite about it but not anywhere near as funny. Hahahaha
