I have been working on a Flash version of a Scientific Calculator

And I just (foolishly) uploaded it on top of the old javascript one (which had some bugs).

It seems to work. And I am conducting lots of test on it, but the developer is never a good tester.

So could you guys give it a thorough working over and let me know any problems?

1. The calculator is unable to compute 171!, which means the calculator has an upper limit of 307 or 308 digits. The factorial function seems to work perfectly

2. There are some functions which are in addition to the ones found in a standard scientific calculator, such as all the 'Functions needing two values', lograithm to the base b etc. This is an additional feature, and **a good one!**

3. Certain functions like

are not available. is missing!4.

may also be added, if possible. Further, conversion frm Polar to rectangular coordinates and vice versa isn't available.5. Binary, Octal, and Hexadecimal systems are missing. These aren't an absolute necessity though. Similarly, Logic operations 'And', 'Or', 'Not', 'Nor' etc. are not available. Operations on Complex numbers too cannot be performed.

The functions which are presently not available may be added, if feasible.

**The bottom line is, it is a Great effort, and has yielded a wonderful result.**

Thanks ganesh! I will try to tackle some of those features in the next release.

As an ordinary calculator, its good enough. But for it to be a SCIENTIFIC calculator, then I think some of the things mentioned by Ganesh should be included.

Can you please explain how and where a "flash" calculator is loaded, and indeed where a Javascript version is loaded? If I'm told that, I may be able to try yours out.

The Scientific Calculator is in "flash"

I got it to say

1*1-------8/=-Infinity

and

3.14159265=Infinity

What did I do? I just typed random numbers.

Look at the "Interpreted Formula" to see what it is doing.

For example "8/" ends up being "8/0"

I guess "Infinity" is wrong ,,, it should be "undefined".
