Changes

Fixed

• Allow any name before ?
• Correctly separate unit prefixes from currencies
• Fix thousands separator when the number has a sign

Changed

• Don't add spaces around ^ in formatting
• Unit conversion data is now generated from the file /calculator/unit_data.txt, making it easier to add new units, even for people who don't know Rust

Name

• Changed to "funcially"
• Logos changed
• Official website at funcially.com
• Experimental version now found here

Added

• GUI: Show shortcuts in "Edit" menu

Changes

Fixed

• Allow using + and - without spaces (e.g. 1+2)
• Correctly handle brackets in function arguments
• Don't allow using the function being re-defined in the re-definition
• GUI: Link source code + wiki
• GUI: Fix spelling mistakes
• Add currency data updating on startup for web app
• GUI: Fix issues with copying

Changed

• GUI: Output text sliding was replaced with a hover tooltip

Added

• GUI: Line numbers for input & output lines
• Allow using _ as the thousands separator in literals
• Formatting the output with _ as the thousands separator
  • Checkbox in "Settings" window in GUI
  • Command line argument for CLI application
  • "raw" parameter for Discord command
• GUI: Formatting
  • Format with correct spacing
  • Remove leading & trailing zeroes from numbers
• Experimental version
  • Can be accessed here
  • Is up to date with the main branch (might thus be unstable)

Changes

Fixed

• GUI: Use NaN (Not a number) instead of infinity in the plot if the function is not defined for the current x-value
• Allow using previously declared functions & variables in other custom functions
• GUI: Correctly highlight wrapped lines
• Allow function invocations in function arguments
• Correctly format units in UnknownConversion errors

Changed

Name

• Changed name to "axioma"
• Added logo

Added

• Information for Unknown* errors
• Windows installer + MacOS installation drive
• Shortcuts
  • ("Cmd" is "Ctrl" on Windows and "cmd" on mac)
  • Cmd+Shift+0 to comment / uncomment lines
  • Cmd+B to surround selection with brackets
  • Cmd+Shift+C to copy the result of the current line
• GUI: The plot now has a legend

Discord bot

• Calculate an input string using /calc <input>
• Sessions:
  • Sessions are threads, in which calculations use the same environment, meaning functions declared further up can be used in later calculations
  • Create a session with /session create <name>
  • Delete the session with /session delete <name> (if invoked from inside the session thread, the name may be omitted)
  • Sessions are persisted across bot restarts

Changes

Fixed

• Make updating the downloaded website automatically (it will download the new version on first reload, then apply it on second)

Changed

Added

Changes

Fixed

• GUI: When a function has been redefined, previous versions can now still be plotted
• Don't crash when rounding big numbers
• Prevent a crash when brackets don't match
• GUI: Don't crash if a function is not defined for an x-value (e.g. f(x) := 1 / x is not defined for 0)

Changed

• In equality checks & equations, the calculator now tries to convert the units of the left hand side and the right hand side (making e.g. 60min = 1h correctly result in True)
• Allow numbers in identifiers (e.g. f1(x) := ...)

Added

• Write a backtrace file on crash
• round, cbrt and root(<root "index">, <number>) functions
• GUI: Persistence
• << (Bit shift left), >> (Bit shift right) and mod operators
• Scientific notation support (e.g. 1e3 => 1000)

Solving linear equations

• The calculator can now solve linear equations if there is a question mark (?) on either side of the equals sign (=)
• Question mark position restrictions:
  • It or its enclosing groups cannot be surrounded by a power sign, since that would make the equation non-linear
  • The question mark can only be an argument of custom functions that are themselves linear
• Supports formats (after either sides)
• Supports units (e.g. ... ?km ...)
• Storing the question mark's value in a variable, using the syntax ... <variable-name>? ... (e.g. 3 + x? = 30 => x = 27)

Changes

Fixed

• Infer multiplication if group is empty (e.g. 3())
• Use the correct unit after variable resolution (e.g. pi km)
• Allow decimal places if the number has a sign
• Use the correct unit after function resolution (e.g. sin(30)min)

Changed

• Units are now case-sensitive
• Unit prefixes can now be used on their own (e.g. 3k = 3000)

Added

• CLI: Use colors in output
• GUI: PWA downloading instructions for Safari
• GUI: Settings window with debug rendering options
• GUI: Ability to dump debug info for the current line
• Added more units, including units with a power (e.g. m^2)
• Support for units that are built out of two other units, delimited by a /. These units are fully user-chosen and conversions are supported (e.g. km/h)
• Support for currencies
• Matching brackets are now highlighted in the same color

Changes

Fixed

• Fix issue with website crashing

Changed

Added

Changes

Fixed

• Crashes with non-ascii characters
• Allow the use of function arguments in the function body in groups / other function calls.

Changed

• More detailed error messages.
• GUI: Lines in the output column now automatically scroll if they're too long to fit

Added

• GUI: Lines in the output column can now be selected and copied by clicking.

GUI: Plot

• There is now a button at the top left of the window, toggling a plot on the right.
• Functions with one argument now have a checkbox in the output column, allowing the user to select whether to show them in the plot.

Web App

• The GUI version of the app is now available on the web.
• The web version can also be made available offline as a Progressive Web App (PWA) (e.g. if not on desktop)
  • The on-screen keyboard on phones / tablets unfortunately does not work flawlessly. Using an external keyboard is recommended.

New in this release are custom functions and custom variables, along with various smaller bugfixes.
