Polish Notation Calculator

A calculator program that accepts input in Reverse Polish notation.

Implemented in Gleam, a type safe functional language that runs on the Erlang VM.

Features

  • Postfix Notation: Allows users to input expressions where operators follow the operands, eliminating the need for parenthesis.

  • Variable Registers: Supports a customizable amount of variable registers (x1 to x10 by default), allowing users to store values in memory.

  • Register Assignments:

    • x1 5 =: Assigns the value of 5 to the x1 register.
    • 2 x1 5 = *: Assignments return the register value, allowing the use of assignments as an argument for another operation

  • Example Operations:

    • 1 2 +: 1 + 2
    • 3 2 1 + *: (1 + 2) * 3
    • 1 2 3 * +: 1 + 2 * 3
