Implement new Concept Exercise: integral-numbers

[ErikSchierboom]

This issue describes how to implement the integral-numbers concept exercise for the F# track.

Getting started

Please please please read the docs before starting. Posting PRs without reading these docs will be a lot more frustrating for you during the review cycle, and exhaust Exercism's maintainers' time. So, before diving into the implementation, please read up on the following documents:

• The features of v3.
• Rationale for v3.
• What are concept exercise and how they are structured?

Please also watch the following video:

• The Anatomy of a Concept Exercise.

Goal

The goal of this exercise is to teach the student the basics of the Concept of Integral Numbers in F#.

Learning objectives

• Know of the difference between signed and unsigned integral types.
• Know of the existence of the integral types: sbyte, byte, short, ushort, int, uint, long and ulong.
• Know when to use which integral type.

Out of scope

• BigInteger.
• Overflows.
• Units of measure.

Concepts

This Concepts Exercise's Concepts are:

• integral-numbers: know of the difference between signed and unsigned integral types; know of the existence of the integral types: sbyte, byte, short, ushort, int, uint, long and ulong; know when to use which integral type.

Prequisites

This Concept Exercise's prerequisites Concepts are:

• numbers: define numbers and apply arithmetic and logic to them.

Hints

• Integral number types: which integral number types there are and how to use them.

After

• Integral number types: which integral number types there are and how to use them.

Representer

This exercise does not require any specific representation logic to be added to the representer.

Analyzer

This exercise does not require any specific logic to be added to the analyzer.

Implementing

To implement this exercise, please follow these instructions.
