Ideas for my program

[madamerouge1331]

I am currently writing a program called Math Cheater's Dream, which basically has many functions that normal calculators do't have. Does anyone have more ideas for functions? I currently have:

Find GCF or LCM
Divide and find remainder
Find prime factors
Find volume of several 3-d shapes, as well as area of several 2-d shapes
Find factorial
Convert between Celsius and Fahrenheit
Generate random number

Any suggestions?
The program can be downloaded at mathcheatersdream.webs.com.

For GCF, use the Euclidean Algorithm - my recommendation. For dividing and finding remainder, basically %. For factorial, use a recursive function - I just like the recursive version better. If not, do a loop. For the volumes, excellent idea! For conversions, do the obvious.

Also, what programming language are you using? I have done most of the above in C.

You could add:


A height equation for an object that is thrown through the air based upon initial height, initial velocity, and angle thrown.

More conversions (Tons of things to do with this, not just simple kilo to deci stuff but also higher level conversions of polar to rectangular points and things along those lines)

probability equations

etc.

To Ahaanomegas: I already have every one of these functions, I am looking for more. I am using C++.

You should implement arbitrary number sizes. (BigNum type)

To restate, a type that can hold a number with an arbitrary number of digits, from 0 to several googol, space permitting.
