Calculator - Scientific Calculator Chrome Extension | Melanto

'Calculator' is a unique, scientific Chrome extension designed with touch-screen and keyboard-friendly interfaces. It stands out for showing both operands during computations (eg: 2 + 2), until '=' is clicked. This calculator handles basic operations and advanced functions such as trigonometric, logarithmic and exponential calculations. It further features memory buttons, copy/paste functionality, root calculations, rounding options, and more. The design is customizable from three themes. Note: this extension requires copy/paste permissions.

Extension summary

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)

User reviews
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.

very good

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.
