I need some ideas...

Hey all,

I'm compiling a rather large calculator based on some (come to think of it, it'd be //most//) of the stuff I've learned in my math class last year. I'm trying to think of anything else I should include in it, but alas, I've gone blank.

I know that all the differing variables are probably taking up too much memory, and I //do// plan to tone it down to about maybe three variables in the end, but can anyone help me with some ideas? I can't think of anything else to add...

Here's the code:

I'm not asking anyone to finish the code - that's my job - but I'm just asking for some ideas I can use... Any input is very much welcome.

I'm still pretty new to this board - I forgot about the code insertion operators... here's the code again, hopefully it'll come out right...

PS: Sorry 'bout that...

Well, you can do exponents, fraction conversions (break down the fractions to smaller fractions), linear equations, and slew of other stuff like square root conversions (same as fraction conversions, but with square roots)

Why do you use the switch statement only once???

it hadn't hit me to use the switch statement more than once... Thanks, I'll get on it ASAP!

damn!
this is like a novell!!!
:)

Okay, I tried the muliple case statements, but I keep getting an error that states the case value '1' is not allowed, or something to that effect.

Oh, and sorry 'bout the length of it... I needed to shorten it up anyway... :cool:
