Pud

Human friendly calculator app for Linux

This is a working in progress project.

Introduction

Pud is a calculator app for Linux that tries to emulate natural language for describing the equations, it also allows taking notes with the math. With Pud, you can write things like this:

This delicious ice cream costs 5.0 plus 0.25 after taxes // Pud evaluates to 5.25

Grammar

Pud has a special grammar so math and text can come together.

Everything that can't be parsed into an expression is a text, so there are no reserved keywords, here are some expressions you can write with Pud:

Basic Arithmetic

• Addition:
  • 2 + 2
  • 5 plus 10
  • 6 with 4
• Subtraction:
  • 2 - 2
  • 5 minus 10
  • 6 subtract 4
• Multiplication:
  • 2 * 2
  • 5 mul 10
  • 6 times 4
  • 3 multiplied by 6
• Division:
  • 3 / 2
  • 10 div 5
  • 6 divide 4
  • 7 divided by 7
• Power
  • 2 ^ 2
  • 3 ** 4

Floating Point

Pud supports single precision floating-point math, so you can calculate 2.3456 + 3.4, if you omit the decimals Pud will do his best to evaluate the answer to integer. For example:

• 2 + 1: answer is an integer because both terms are integer.
• 2.5 + 1: answer is a float because one of the terms is float.
• 5 / 3 or 2 ** 5: always evaluates to float for the sake of simplicity.

TO-DO

• Graphical User Interface
• Speed, Distance, Temperature and Time conversions.
• Advanced math functions: ln, exp, etc.
• Currencies and Cryptocurrencies conversions.
• .deb and .rpm packages.
