Powerstone Program

Nope. Source has been provided, and binaries for the two most popular desktop platforms has been provided. I would advise that you need to link against the math libraries (-lm in standard usage) for pow to be found.

Is there a reason that you're using codepad.org instead of one of the free compilers for your platform? I doubt that codepad.org is capable of using the code I provided. It lacks provisions for command line parameters and for libraries besides libc. It needs libm.

If the code runs at codepad.org, you can ship it with an URL, and just about anyone with a browser can use it. There's also less of a trust or security issue for whatever reason. I personally was trying it out there to see what was platform-specific, and also since I'm away from by my dev machines during the weekend.

And codepad.org still has some new shinny left on it for me, or had before the apparent omission of some math functionality was revealed. :(

Unless I've missed something at codepad.org, the inability to link against the standard libraries isn't the only problem—although, that's a doozy. Say someone did write you a version which replaced pow()—and yes, that's easy enough to do—how do you interact with the program at codepad.org? I haven't dug into every nook and cranny, but I haven't noticed any way to provide input to a program. For powerstone.c, you'd always be looking at its usage message, and that's not terribly useful.

Well this thread has inspired me to finally build my GURPS Enchantment Calculator

Bah. Why am I using google when I've got javascript? This version doesn't require an internet connection, just any javascript-capable browser:

javascript:c=prompt('Powerstone%20Capacity:','');if(/\d+/.test(c)){(10*c*c+40*c)*Math.pow(54/53,c)+20*c}else{null};

I plug that into Chrome, it produced the prompt, but not the results.

You can also just use a scientific calculator. Anyway, here is a google docs spreadsheet that calculates most of the stuff you want to know (you'll have to copy it; I didn't turn on edit access). Note that the price listed is per the formula in Magic, which is not quite correct, but the correct formula is messy to calculate and not different enough to really matter.

Oops. Firefox was being too nice about my bad coding. Try this:

javascript:c=prompt('Powerstone%20Capacity:','');if(/\d+/.test(c)){d=document.open();d.write((10*c*c+40*c)*Math.pow(54/53,c)+20*c);d.close();}else{null};

Works in Firefox, Chrome, and Safari on my mac.

There's nothing platform specific about the source code I provided. For that matter, the windows binary I provided uses Qt, which means it can be rebuilt to provide a GUI for most common operating systems, including iPhone and Android.

When you wrote "windows version" earlier, I was mistaken about exactly which item it referred to.
