Hey Guys: Your Gamma function is badly wrong!!!!. Compare 10.5! to an HP scientific calculator.

In many respects the web2.0 calc is an excellent calculator.

If you look in the reference material sticky thread there is a section near the beginning on different web calculators.

Different calcs are good for different purposes. :)

tell me the best digital calculator plz...???

Yes, I am aware that there may be a problem with the Gamma function.

I have let admin know :)

Hey Guys: Your Gamma function is badly wrong!!!!. Compare 10.5! to an HP scientific calculator

Try this Java-written cal:http://www.alpertron.com.ar/BIGCALC.HTM

This site calculator only looks puny to you because you not know how to use it.

NO!!!!!. The reason yours looks puny is that the Java calc, can handle answers up to a 1000,000 digits long & exponents of 10^10!!!!!!!!!!. Can yours do that?

Here is the answer to 10.5! from the Java calculator I mentioned to 500 digits:

11899423.0839622484 5701302873 8683370993 3831322368 8917765439 1595852559 5755955880 4361403512 0656639876 5519126778 5285937899 2016340591 8183698040 6477895148 6478310200 1359101153 0263746200 5444491936 3566290158 4151853275 2752288646 3750295799 2551913979 9994637865 8694270667 1265852424 2758484369 1216399060 9437036897 6637471050 2766924888 0891181898 3814965781 2154288176 8619126809 2952304232 1889341549 8736005658 2862175374 8771364283 1409580432 0462253315 1985088377 0720270695 2877194437 2274510447 5279632178 1247006050 4126855260 05

OK first you do know that 10.5! is not Γ10.5?

Second it's cool it can give that many digits but why would you need a million digits? or even a 100 of them?

I know that SOME calculators subract 1 from the number you enter & take its gamma value. But that's irrelevant!. If you are interested in "Number Theory" you need to take the factorial of 10^6!for a variety of reasons!!. And it's nice to know THERE IS a calculator that can do that FOR FREE!. You can always buy a math package, such as Wolfram, which will cost you hundreds of dollars, to do the same thing.....etc.

A factorial of 10^6! would take a long time for even super fast computer to do. The java program would take weeks if it do it at all.

Are you one of the developers of this calculator? If not, why are you so defensive about an online calculator that's defective?. It HAS a mistake in it & help to correct it!.Don't try to justify a mistake on a calculator, especially a very important function in Math such as Gamma function. It "doesn't take forever to calculate 10^6!. Besides, you may need only, say, the 1st. 1000 digits to compare it, for example, to an asymtotic formula, such as Sterling Formula to find out how accurate your approx. is. Just for you info, I ran the first 10,000 digits and it only took it a few seconds!!!!!!!.

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
