Factorio / calculator-ui

  # Changelog
  All notable changes to this project will be documented in this file.
  
  The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
  and this project adheres to the versioning of Factorio, so 0.18.x will be at least compatible / tested with Factorio 0.18.x.
  
  ## [Released]
  

  ## [0.18.5] - 2020-06-08
  Added some fancy sound effects and a special [Nilaus](https://www.youtube.com/c/Nilaus) mode.
  
  ### Added
  - Added sound effects to the calculator whenever a result may be not the desired one (has be enabled in the settings)
  
  ### Changed
  - Emotes will no longer be displayed at default, "Nilaus mode" has to be enabled for the emotes to appear again
  
  ### Fixed
  - Recent results weren't properly cleared in 0.18.4
  
  ### Misc
  - Some code rework, not too fancy stuff
  

  ## [0.18.4] - 2020-06-07
  ### General

  Based on user feedback updated the mod
  
  ### Added
  - Added the possibility to copy the results (from recent and also the current) to the display

  
  ### Changed
  - Window now remember last location when opened

  - Updated the BS button (it's backspace people...) so it now has a nice icon instead of the letters
  - Recent results now add to the top, instead of the bottom
  - When calculator is opened it focues on the display for entering the equation
  - You can click pretty much anywhere now and it focues on the display for entering the equation

  
  ### Fixed
  - On multiplayer session the window would lag behind while dragging, because the location would be saved on server. This isn't going to happen anymore, hopefully (not tested yet).
  - When window is moved out of boundaries, when reopened, it will correct itself to be fully in sight again.

  - Settings had weird default values (were set 2 times)

  ## [0.18.3] - 2020-06-07
  ### General
  A small visual overhaul of the mod
  ### Added
  - Added the possibility to "calculate further" (especially usefull when setting "Clear equation on calculation" is set). When the equation doesn't start with a number, character or parenthesis (so it assumes it starts with a math symbol) it will take the previous result and prepend it to the current equation.
  
  ### Changed
  - Updated the UI a bit to match it in color a bit more to the Windows calculator
  - Updated also the icon on the shortcut to better distinguish it
  

  ## [0.18.2] - 2020-06-06

  ### General

  Based on user feedback updated the mod

  ### Added
  - new easter egg :-)
  - added more math.lib functions
    - atan2() -> math.atan2()
    - cosh() -> math.cosh()
    - sinh() -> math.sinh()
    - tanh() -> math.tanh()
    - log10() -> math.log10()
    - fmod() -> math.fmod()
    - frexp() -> math.frexp()
    - ldexp() -> math.ldexp()
    - pow() -> math.pow()
  
  ### Fixed
  - Interpreting ";" as "," in the equation, because of the fix in 0.18.1, so that math functions with more than 1 parameter work. They have to use ";" as a separator for inputs
  - Fixed sqrt(-1) equaling "na" because of the rounding fix from 0.18.1. It does now show "NaN" again
  

  ## [0.18.1] - 2020-06-06

  ### General

  Based on user feedback updated the mod

  ### Added
  - Shortcut for opening the calculator and automatically focus on the input (Default: Ctrl+Shift+C) 
  
  ### Fixed
  - Rounding removed 0 at the end, will now stand as it should. So 2.0000001 -> 2.00
  - Interpreting "," as "." in the equation, because of some European countries do have a weird keyboard layout
  

  ## [0.18.0] - 2020-06-06
  ### General
  - Initial Release of the mod 
  - Compatible with Factorio >0.18.0; tested on 0.18.30
  - Based on the 4-Function Calculator found in the [Max Rate Calculator](https://mods.factorio.com/mod/MaxRateCalculator) mod by [Theanderblast](https://mods.factorio.com/user/theanderblast)
  
  ### Added
  - History of recent calculations
  - Possibility to copy recent calculations to the current one (with shift+left-click)
  - Substitutes some functions & "constants" of the Lua [math-lib](http://lua-users.org/wiki/MathLibraryTutorial)
    - abs() -> math.abs()
    - acos() -> math.acos()
    - asin() -> math.asin()
    - atan() -> math.atan()
    - ceil() -> math.ceil()
    - floor() -> math.floor()
    - cos() -> math.cos()
    - sin() -> math.sin()
    - tan() -> math.tan()
    - deg() -> math.deg()
    - rad() -> math.rad()
    - exp() -> math.exp()
    - log() -> math.log()
    - min() -> math.min()
    - max() -> math.max()
    - modf() -> math.modf()
    - sqrt() -> math.sqrt()
    - huge -> math.huge
    - pi -> math.pi
  - Allows the use of "%" (percent sign) in the calculation
  - A little easter egg :-)
  - Setting for number of decimal places in result (Default: 2). Exact value will be displayed in the tooltip
  - Setting if triggering the calculation should clear the current equation (Default: no)
  
  ### Changed
  - Made the buttons slightly bigger, so that it's better readable on streams.
  - Allows to make "complex" calculations with parentheses
  - Allows pretty much all characters in the equation field
    - but the "=" (equal sign) will trigger the calculation
  
  ### Removed
  - Got rid of the memory functions - but introduced the list of recent calculations instead
