Javascript Algebra Calculator

algcalc's Issues

My Internet Is Back

Original post:

I post this from the library. I may or may not keep working on this until it is fixed. (No mobile data, 4 hour WiFi limit at library)

Half-width cards too narrow on mobile devices

They will eventually resize to be full width.

Make root and power more robust

Currently they eval everything in the formula box, and then run the function. They should support being parts of the formula.
Applies to sqroot, abs, x^2, sin, cos, tan, log, etc.

use html5 <nav> instead of <div class="bar" id="mainbar">

Might as well stay consistent and use html5

Consider CSS Grid

Consider using CSS Grid as it can do a table-like layout and is responsive.
However, backwards compatibility can be a problem.

Footer

The footer isn't quite ideal yet (it could use some styling and position work and needs to be implemented on all pages).

However, it could be an easy workaround for #39 by providing the same background color as the menu to fill the gap.

Verify order of operations work

I quickly tested it, but it should be thoroughly tested.

Set up GitHub Pages

Set up GitHub Pages so there is a live preview.

Javascript Outline

Here is what the most basic javascript will look like:

• Get input
• Separate constants and operators
• find order of operations
• solve one step at a time

Menu only works on homepage

Navigation Menu only works on homepage.

drop shadow on dark theme invisible

matches background colors

Oversize Navigation bar. & move GitHub button to navbar

The navigation bar is to big for my liking. I also think that the view on github button needs to be in the navigation bar.

Calculate page

Here is a quick mock-up for a new page.

Use Calc API instead of Eval()

The eval() function can't solve for variables or solve step by step. We need to write a script that feeds one step at a time.

What Information For Develop Page?

What information do we want on the 'Develop' page?

• Username (with link to site)
• Name*
• Hobbies
• How they helped

*Maybe

Icons to Svg

The text one isn't supported by some devices and looks different on each browser. I have the svg version of the original settings icon.
Here is the current ones for me:
Chrome
Firefox
See, They're different.

Sub menus?

We should add sub menu support.

Calc API

I have decided to make a separate repository for calculations, as it will make this project more useful to everyone. (and it'll sure beat the use of eval)
I hope to hear from you at https://github.com/chexbox/Calc-API !

Please note: Continuation of this repository will most likely continue as planned.

Close Basic Calculation Milestone?

Should I?

Side menu reaches past bottom of page now

Also, consider using a different positioning for the bar when the menu is out.
It doesn't look right on IE.

Look into using Bootstrap

As mentioned in #11

Make post on Scratch Advanced Topics

Should we? There are some talented people there.

Root and power keys should be configurable

To allow different roots and powers than 2.

Pages to come

Definitely coming

• FAQ

• How to use

• Contributors

Possible pages

• Pages for different calculators (ex. basic, scientific, algebra, graphing, etc.)

Root key does not work

Official Place to Ask Questions for FAQ!

This is the official place to ask questions (that are unrelated to developing).
Ask questions for the FAQ in the comments below.

HTML/CSS Confilict

HTML: class="key small"
CSS: .key-small
notice the "-" in the css.

Undesired float drop on navbar

Maybe create a dropdown menu?

Remove sticky from bar at top

On mobile devices it can take up too much space. I think we should keep the bar, but make it scroll with the page.

Any comments?

replace separate pages with # in url

With Javascript you can use window.location.hash to read a hash at the end of a url window.location.hash would return '#simple' for the url https://chexbox.github.io/Algebra-Calculator/#simple

We would use this to get calculators from different iframes.

Make sure buttons line up correctly

They don't on mobile.

Choosing a license

We should associate an open source license with this.

(Oops)

Buttons

What buttons should we have?

• 0-9

• .

• /

• =

• x^2

• x^3

• x^x

• square root

• cubed root

• x root

• History?

• previous answer

"Calculate" instead of "="

The equal sign will get used later for algebraic calculations, so I think we need a full-width calculate button at the bottom.

Choosing a Colour Scheme

I'm not sure I like our use of colour as it is too close to scratch's colours. Discuss below possible replacements. (Green?)

Design

We should work out a couple of sketches.

Add Privacy Policy

Cookies, what we don't collect, etc.

Empty shown.not big enough

See CSS / preview

Fix "View on Github" Button

The formatting on the button that goes to the Github Repository is broken.

New repository for calculations?

I am considering opening a JavaScript only repository that would replace our use of the eval function.
Any thoughts about this?

Disabled Keys can still be Used

sqrt key and ^ key

Name ideas

Just some ideas:

• jsCalc

• WebCalc

• OpenCalc (there is an old calculator with this name)

• Calc.js

• OpenAlgebra

Needs <title> Tag

Needs title tag in header to name the tab.

Use Algebra.js parse until Calc-API finished

http://algebra.js.org/#parser

Animations on dropdown are broken

I broke them while dealing with too-long menus.
I think we can use this as an opportunity to put something more robust in place.

settings drop-down on right

Replaces use of change theme section on homepage.

Complex buttons?

Do we place buttons for complex calculations, like variables? I think we should keep the buttons simple calculator only.

Things are quite broken on Edge and IE

Whoops.
FF and Chrome seem to be working pretty well, however.

Power Key Gives Unpredictable Results

Eval doesn't work too well. Disabling for now.
