Desafio Técnico-Elixir

Precisamos de pessoas com energia, integridade e inteligência, que aprendam rápido e que gostem de conhecer e aplicar novas tecnologias.

O tempo sugerido para conclusão do desafio é de 15 dias. Queremos que você se dedique e demonstre a qualidade de seu código.

Bom desafio!

O Desafio

O Sistema Financeiro precisa representar valores monetários. A ideia básica é ter uma estrutura de dados que permita realizar operações financeiras com dinheiro dentro de uma mesma moeda. Isso é pelo motivo de pontos flutuantes terem problemas de aritmética, logo encodificamos valores decimais/fracionais/reais como uma estrutura de dados com campos em inteiros, além de mapeamos operações aritméticas sobre tal estrutura. No fim, a implementação acaba sendo uma Estrutura de Dados Abstrata.

Architecture

• Use Onion architecture

  • Dependencies go inwards. That is, the Core domain doesn't know about outside layers

• Use pipeline model to implement workflows/use-cases/stories

  • Business logic makes decisions
  • IO does storage with minimal logic
  • Keep Business logic and IO separate

• Keep IO at edges

Thanks everyone for commenting/contributing! I made this in college for a class and I no longer really use the technology. I encourage you all to help each other, but I probably won't be answering questions anymore.

This article is also on my blog, too.

Steps to Install Anaconda on Windows Ubuntu Terminal

1. Install WSL (Ubuntu for Windows - can be found in Windows Store). I recommend the latest version (I'm using 18.04) because there are some bugs they worked out during 14/16 (microsoft/WSL#785)
2. Go to https://repo.continuum.io/archive to find the list of Anaconda releases
3. Select the release you want. I have a 64-bit computer, so I chose the latest release ending in x86_64.sh. If I had a 32-bit computer, I'd select the x86.sh version. If you accidentally try to install the wrong one, you'll get a warning in the terminal. I chose `Ana
