NumeralSystems.Net 3.0.0

NumeralSystem

This library is inteded to simplify the creation/usage of numeral systems.

Usage

Creation of numeral system

To create a numeral system by It's construnctor you must define an identity of unique elements and a string separator.

public NumeralSystem(HashSet<string> identity, string separator = ";")

Otherwhise you can create a numeral system with the identity dimension by calling:

public static NumeralSystem Numeral.System.OfBase(int value, string separator = "")

Like so:

var binary = Numeral.System.OfBase(2);

Indexing a numeral

You can get a numeral from It's index (int or float):

var valueA = binary[12];
var valueB = binary[1.2f];

Parsing a string

You can parse a string to It's numeral representation with the StringParse method:

var valueC = binary.StringParse("1100");

Conversions

A numeral can be converted to:

• An integer

  var a = valueA.Integer;

• A double

  var b = valueB.Double;

• A decimal

  var d = valueB.Double;

• A string

  var c = valueC.ToString();

• A number of another base

  var d = valueC.To(Numeral.System.OfBase(5));

Customizations

You can create your custom Numeral System by providing:

• A custom string parser.

  By calling the setter of "Func<string, Numeral> StringParse" in the NumeralSystem class

• The indexing mechanism.

  By calling the setter of "Func<int, bool, List<string>, List<string>> IntIndexer" in the NumeralSystem class

• The string conversion mechanism.

  By calling the setter of "Func<(List<string> Integral, List<string> Fractional, bool IsPositive), string> StringConverter" in the NumeralSystem class

• The negative simbol.

  By calling the setter of "string NegativeSign" in the NumeralSystem class

• The CultureInfo (That provides the default symbols for negative and floats)

  By calling the setter of "CultureInfo CultureInfo" in the NumeralSystem class

• The Float symbol.

  By calling the setter of "string FloatSign" in the NumeralSystem class

• The Separator. (If the string representing the value is longer than 1 char)

  By calling the setter of "string Separator" in the NumeralSystem class

UnitTest

To test the functionalities you can use NumeralSystem.Net.NUnit

Test

To test the implementations you can use the UI project NumeralConverter that features a conversion from base to base.
