This is a PWA developed with HTML, CSS and JavaScript to calculate operations with some extra features. It has offline functionality so you are able to use it without an internet connection, but keep in mind that only works properly with Google Chrome. Furthermore, it should be mentioned that there is a background functionality on settings, but it is only available on PC and tablet. Certain functions have been implemented using Qr-scanner (Only available through HTTPS protocol) and Exchange Rate API.

Get rid of your boring old calculator and enhance your math operations, through a fully customizable experience with a ton of extra utilities.

Unlock your artistic side being completely creative without limitations. Hide items or buttons you don't like by using the same colours, express yourself, and share your themes with friends.

Although this is not an entirely scientific calculator, you can make any operation you want and use some features and buttons that you expect on your daily life. Most of them can be used with a keyboard, mouse or touching the screen and they are divided into four broad categories:

• Memory:
  
  

  M+	Adds the current result to stored result.
  M-	Subtract the current result from stored result.
  MR	Get stored result as an operational value.
  MS	Save the current result to memory.
  MC	Delete stored result.
  CE	Delete current result.



• Functions:
  
  

  LOG	Compute the logarithm of the specified number or operation.
  SIN	Compute the sine for the radials of the specified number or operation.
  COS	Compute the cosine for the radials of the specified number or operation.
  TAN	Compute the tangent for the radials of the specified number or operation.
  PI	Invoke an amount equal to PI.
  SQR	Calculate the square root of the specified number or operation.



• Regular:
  
  

  Numbers (0-9)	Choose any number from 0 to 9.
  Decimal point	Convert all combinations of numbers to decimal.
  Parentheses	Use open and closed brackets to segment operations.
  Percentage (%)	Apply percentages or calculate leftovers from a division.
  Circumflex (^)	Raise values to other numbers or operations.
  Asterik (*)	Multiply any combined numbers or operations.
  Slash line (/)	Divide any combined numbers or operations.
  Add (+)	Sums any combined numbers or operations.
  Subtract (-)	Convert values to negative or subtract any combined numbers or operations.
  Equal (=)	Display the result.
  DEL	Remove a character and display a new result.
  AC	Reset all values.



• Special:
  
  

  Power	Turn on or off your calculator.
  QR Reader	Read a QR code using a camera or supplying a file.
