Flical (FLIpped CALculator)

A work in progress

If you like, fill out this short questionnaire on Google forms with four questions about calculators and RPN. This helps me to find out what people care about. Thank you! I plan to publish the results after some time.

The state of things

• Basics work
  • reals, fractionals and complex numbers
  • simple arithmetic operations, frac, int, round, abs
  • inbuilt documentation
  • key mapping
  • mode ALT and INV
• AppImage bundling with Tauri works
• Todo
  • more operations (trigonometrics, roots, powers, logic, etc.)
  • stack management
  • more testing
  • configuration by user
  • extensions
  • home page

Goals

• Small and simple but complete online RPN calculator
• Extensions for the A-F buttons by external libraries, for example:
  • A => scientific constants
  • E => statistics
  • F => boolean operations for 64 bit integers (fraction with denom 1)

Features

• 26 keys
  • Basic arithmetic operators
  • Stack management and registers
  • Backspace and undo
  • Elementary mathematical functions
  • Display, percent, random number, decimal time, truncating, factorial
  • Hexadecimal letters A to F, also used as function keys
  • Mode key (ALT and INV)
• Stack with four places (x, y, z, t)
• Sixteen registers
• Display with four rows of 35 cells
• Number types
  • double precision IEEE 754 numbers
  • fractions on 64 bit integers
  • complex numbers on double precision IEEE 754 numbers

Development

• Rust
• Trunk
• Webassembly
• Tauri
• No framework
