ZoomCalc - Online instant notepad calculator program

Post by Rambus »

Hello Ogre(s),

I thought I would share a neat online calculator I wrote to help people working out numbers / doing quick math. It's a cross between notepad and a spread sheet. It's ideal for working out quick and dirty math, because as you type it computes the result. You can reference rows (R1) just like in a spread sheet, or you can store values in variables, e.g. X=123.

I wrote it for myself, for when I'm programming and I need to derive some expression. But I packed in the ability to save and share calculators to try to make it more useful for the entire community.

You can check out my program here: http://www.ZoomCalc.com

Here is a simple example for computing Win/Loss ratio:

Here I calculate the number of attacks required by a Zergling to kill a Zealot in the game Starcraft 2. This should show you how you could compute more complex things.

Heres the link:

This calculator is read only, simply click Create Copy to edit it.

Currently the calculator supports:
sin(X), cos(X), tan(X), asin(X), acos(X)
atan(X), atean2(X), sqrt(X), log(X)
abs(X), ceil(X), floor(X), round(X)
exp(X), random(X), fac(X)
min(X,Y), max(X,Y), pow(X,Y)
+, -, *, /, %, ^, ||

Your some of the first people I have shared this with, so please rip it apart and provide constructive feedback

Cool. I've worked with game system designers that crunch a lot of numbers, who would really dig something like this.

+1!
I can see a lot of situations where this tool would have saved me a lot of time, especially when writing shaders. It's now on my bookmarks ;)

I usually just resort to using Python as a calculator when I need to crunch a lot of numbers since the majority of calculator programs out there are awkward to use and have less functionality that my real-life calculator that sits on my desk, but this looks really cool and is much easier to use as a calculator than Python.

I just changed the program to no longer be case sensitive.

@ Miscreant - Let me know if you find anything you find limiting in ZoomCalc compared to using the python calculator.

i like it.

do you have plans to add vector and matrices.
like this,

A = [0, 2, 5]
B = [
[1,1,1],
[1,0,0],
[2,0,5]
]
B * A

i am writing python for these stuff as well.
an online sharable solution would be awesome.

Have you tried Google Spreadsheets? Online, shareable, powerful, and you can edit a spreadsheet simultaneously with another collaborating person and it has MMULT for matrix multiplication :)

Not saying that this calculator doesn't look good - just in case somebody haven't tried the spreadsheets. I've been using them on several occasions were I needed to share some calculations with a client in a easily consumable form and they were top-notch. Basically anybody who has seen an Excel/Lotus spreadsheet will be able to grasp whatever you share with them.

I don't think I will support matrix math in the near term- just because of my limited development hours.

@ bStone - I love google documents! I think they are amazing. I created ZoomCalc because a spreadsheet is not as useful for the kind of 'math figuring' I tend to have to do while programming. I basically wanted a notepad that would allow me to 'think out' math. ZoomCalc's advantages over a spreadsheet are that it instantly presents results as you type, allows for named variable assignment, has a simplified single column design and syntax highlighting. I also think it is a conceptually simpler tool.

But, as you said- if anyone is looking for more powerful column/row based calculations, Google spread sheets are the way to go :)
