Calculator插件简介

This is kinda unusual scientific calculator.

What makes this calculator unusual is that you can see both sides of the current binary operation. For example — if you type 2 + 2 you’ll see exactly “2 + 2” until you press “=”. The calculator was made with touch-screen in mind and should be ready for touch-screen chromebooks.

The app is based on the so called “scientific calculators”, which means it comes with many “advanced” functions (trigonometric, logarithmic, exponential, etc.) But the way that calculator works (different than standard calculators and showing both left and right operand at the same time) means that if you have an operation entered (for example: 5 * 6) and tap some unary operation button (for example the square button) the operation will be performed on the second operand (in our example 6 will become 36). All in all this calculator app will give you little more info for the current/previous calculation but it is still a calculator and not a formula processor or equation machine.

On devices with keyboard you can use the obvious keys: number keys, dot (floating point), +, -, *, /, Enter (=), ESC (C) and Backspace. The advanced (“scientific”) functions are not yet accessible with keyboard shortcuts (but better keyboard support is planned for the next releases).

The initial goal of this calculator was to be a real-life example of jQuery Mobile (and it worked as such) but somehow, with the time, more calculations were added and it became full-featured scientific calculator. It is, however, still work in progress, so let me know if you find a bug, if some calculation isn’t working or if you want to see new feature added.

Basic Calculations:

As one would expect, the “usual suspects” are all here:
– addition (+), subtraction (-), multiplication (*), division (/)
– exponent (Power) operators (3 buttons for power calculation: ^2, ^3 and ^x)
– square root, cube root and general root calculator
– round, round$ and integer buttons
– two ways to do percentage calculations

Of course, here are the good old memory buttons (M+, M-, MR, MC) and you can use the copy/paste functionality too (that’s why the calculator requires copy/paste permissions)

Finally, the scientific calculations supported are:
– sin, sinh, asin
– cos, cosh, acos
– tan, tanh, atan
– cot, coth, acot
– sec, sech, asec
– log10, logN
– ln
– exp
– some constants…

Radians and degrees calculations supported.

Options:

Scientific or not, a calculator needs to be convenient and nice to look at. To make this one better, we added 3 different “themes” for you too choose from. You can change the design theme from the options page. Select between black or white calculator and the original “3d buttons” calculator. (Just click the “options” link at the bottom-right of the calculator popup and select the respective theme from the list)

Other versions of Melanto Calculator

The same calculator is available in 3 different versions: this app (adding calculator icon to the apps page and opening the calculator in its own browser window, simulating “desktop” app), as chrome extension (added to the main toolbar) and as standard chrome app (opens the calculator in new tab) – the “original” calculator. Here are the other two versions:

Calculator App:
https://chrome.google.com/webstore/detail/melanto-calculator/nioffklpggjkmgpndbfklpnclpohpjid

Calculator Extension:
https://chrome.google.com/webstore/detail/melanto-calculator/olhcajgllkpacioibcjiniefblpmpech?utm_source=chrome-ntp-icon

All the 3 calculator versions come with the same calculation engine but I couldn’t create one single to address all the 3 ways of use because Chrome doesn’t allow apps to add icon to the toolbar (so we need the extension), while extension can’t add icon to the apps page (so we need an app) and then, at some moment Chrome offered the “packaged apps” option and I made this “desktop” version for those who want it in separate window, acting as separate app…

Itzel

no its not its way too big to cheat on a test

Anthony

It's not evaluating compound expressions.

Robert

Sounds like you're looking for http://spreadsheet.booogle.net/

Paul

Works well, but the display is much too small for my liking and I would like all the buttons to not be the same colour so I can find things more easily.

网友

very good

Andreas

As others have said, this calculator doesn't respect the algebraic order of operations. This is not acceptable - a calculator has to respect this order, or else it's useless. Please fix this, because otherwise this app is really great, especially since it seems to be the only calculator app that runs outside of the browser. And PLEASE add parentheses and at least some basic user settings.

Maui

It doesn't respect the algebrical order of operations likes 4+5*3=19 the result is 27 the only operation order is how you write your operation. Secondly it doesn't have any ( ) parenthesis and requires authorisation about your copy and paste data I don't know why.

Vladisla..

It's a calculator, not an equation machine. Try one real-life calculator and you'll find it works the same way ;-)

sathika

Good

Heidi

It could only do a one step problem. If you do 4+1*2 the calculator will do 4+1 and then multiply it by 2.

Nathan

I can't edit the problem that I'm trying to solve.

Lusa

Isn't a scientific calculator!

Pablo

I tested it for percentages % & it's 100% stable will recommend 2 anyone!!

Will

works offline as a desktop app. Just what I wanted.

Stefan

This is my favorite calculator. It works offline, has no ads, is pretty, and does everything a calculator should be able to do.

Robert

I was looking for a calculators that is also a Packaged App (apps that run offline and outside the browser)to replace the standard windows calculator and also that would run on a Chromebook. Well this is the App! Its flexible, resizable and has some cool features like copy & paste which is nice if you're working with spreadsheets. Try it out!

Miran

Excellent app!
