Arryn's PD calculator v1.01

[Arryn]

I've put up on my website a Java utility I wrote to calculate PD costs for those that are too lazy to use a calculator, or that don't wish to use a spreadsheet.

The direct link to the file is here.

EDIT: converted into a .jar file for your convenience. Anyone who downloaded the .rar should re-download.

If anyone finds this to be a useful tool, please let me know. Constructive comments and suggestions are also always welcome.

Is it right? It's a bit hard to read on my browser, but I think I can read "10 to 21 costs 165 gold" (?). That should be 176 if I'm not mistaken. I believe the formula is

(1 + initial + target) * (target - initial) / 2

Screenshot of the program showing:

code:

---

Initial PD: 10

Target PD: 21

Cost to raise PD: 165

May I ask you if the image shows the real output?To my knowledge, the cost to raise PD from 10 to 21 is 176, not 165. And for extremely lazy people (like me ) who can't be bothered to start the program to do the calculation, the formula seems to be (n1+n0+1)*(n1-n0)/2. n0 is starting PD, n1 is target PD.

Yeah, I've noticed it too. It must be that the marketing department was producing promotional materials before the program was completed

Fixed. A stupid error. Worked correctly for *even* numbers, and silly me forgot to test with odd ones.

Thanks to the both of you for the catch.

Why test? The formula applies to odd and even number just the same.

Forgive me for saying this, but "why test?" is a stupid question. Lesson #1 in programming: All software needs to be tested, and thoroughly. Just because the *formula* works doesn't mean that the *implementation* of the formula in code works as intended.

Ah OK. And it wasn't a stupid question, only a misunderstanding: I thought you "tested" for even/odd numbers in your code, which of course has nothing to do with "testing" software.
