Comment puis-je convertir un entier en sa représentation verbale?
Existe-t-il une bibliothèque ou une classe/fonction que je peux utiliser pour convertir un entier en sa représentation verbale?
Exemple d'entrée:
4 567 788`
Exemple de sortie:
Quatre millions cinq cent soixante-sept mille sept cent quatre vingt huit
si vous utilisez le code présent dans: en convertissant les nombres en mots C # et que vous en avez besoin pour les nombres décimaux, voici comment procéder:
public string DecimalToWords(decimal number)
{
if (number == 0)
return "zero";
if (number < 0)
return "minus " + DecimalToWords(Math.Abs(number));
string words = "";
int intPortion = (int)number;
decimal fraction = (number - intPortion)*100;
int decPortion = (int)fraction;
words = NumericToWords(intPortion);
if (decPortion > 0)
{
words += " and ";
words += NumericToWords(decPortion);
}
return words;
}
Actuellement, la meilleure, la plus robuste des bibliothèques pour cela est certainement Humanizer . C'est une source ouverte disponible sous forme de pépite:
Console.WriteLine(4567788.ToWords()); // => four million five hundred and sixty-seven thousand seven hundred and eighty-eight
Il propose également un large éventail d’outils permettant de résoudre les petits problèmes de chaque application avec strings, enums, DateTimes, TimeSpans, etc., et prend en charge de nombreux langages différents.
Console.WriteLine(4567788.ToOrdinalWords().Underscore().Hyphenate().ApplyCase(LetterCasing.AllCaps)); // => FOUR-MILLION-FIVE-HUNDRED-AND-SIXTY-SEVEN-THOUSAND-SEVEN-HUNDRED-AND-EIGHTY-EIGHTH
Version entièrement récursive:
private static string[] ones = {
"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine",
"ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen",
};
private static string[] tens = { "zero", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };
private static string[] thous = { "hundred", "thousand", "million", "billion", "trillion", "quadrillion" };
public static string ToWords(decimal number)
{
if (number < 0)
return "negative " + ToWords(Math.Abs(number));
int intPortion = (int)number;
int decPortion = (int)((number - intPortion) * (decimal) 100);
return string.Format("{0} dollars and {1} cents", ToWords(intPortion), ToWords(decPortion));
}
private static string ToWords(int number, string appendScale = "")
{
string numString = "";
if (number < 100)
{
if (number < 20)
numString = ones[number];
else
{
numString = tens[number / 10];
if ((number % 10) > 0)
numString += "-" + ones[number % 10];
}
}
else
{
int pow = 0;
string powStr = "";
if (number < 1000) // number is between 100 and 1000
{
pow = 100;
powStr = thous[0];
}
else // find the scale of the number
{
int log = (int)Math.Log(number, 1000);
pow = (int)Math.Pow(1000, log);
powStr = thous[log];
}
numString = string.Format("{0} {1}", ToWords(number / pow, powStr), ToWords(number % pow)).Trim();
}
return string.Format("{0} {1}", numString, appendScale).Trim();
}
Travaux en cours jusqu’aux quadrillions (à petite échelle). Une prise en charge supplémentaire (pour les grands nombres ou pour longue échelle ) peut être ajoutée simplement en modifiant la variable thous.
Peut-être inutilement complexe (le cas particulier de centaines me gêne un peu), étant donné que modifier la version non récursive est également assez simple.
Voici la version espagnole:
public static string numeroALetras(int number)
{
if (number == 0)

if (number < 0)
return "menos " + numeroALetras(Math.Abs(number));
string words = "";
if ((number / 1000000) > 0)
{

number %= 1000000;
}

{

number %= 1000;
}
if ((number / 100) == 1)
{

else {
words += numeroALetras(number / 100) + " ientos ";
}
number %= 100;
}
if (number > 0)
{
if (words != "")

J'ai été chargé de créer une API Web qui convertit les nombres en mots en utilisant C #.
Peut être un nombre entier ou avec des points décimaux dans 48 heures.
L'appel proviendra d'une application frontale utilisant la méthode Ajax Post et renverra le résultat converti dans la page Web.
J'ai publiquement partagé ce projet dans le GitHub pour référence: https://github.com/marvinglennlacuna/NumbersToWordsConverter.Api
Avec la mise en oeuvre technique suivante en place:
- MVC structuré
- Contrôleur API
- Un service
- Modèle
- La gestion des erreurs
- Test unitaire avec MSTest
- Couverture de code - 98%
- Jquery
Et avec la documentation technique sur les éléments suivants:
- Objectif
- Conditions préalables
- Exigences fonctionnelles
- Diagramme de processus et sortie
** Résultat via la page Web (US-001) **
US-001 Conversion de nombres en mots via un processus de page Web
US-001 Conversion de nombres en mots via une sortie de page Web
Résultat via Postman (US-002)
US-002 - Conversion de nombres en mots via un processus Postman
US-002 - Conversion de nombres en mots via la sortie Postman
Je pense que cela vaut la peine de partager une solution de travail dans le cas où vous en avez besoin pour référence dans une interview/un test de code/une école ou pour le plaisir seulement.

Solution qui prend moins de code.
La partie la plus importante n’est que quelques lignes:
static Func<long, string> remainder = t => t > 0 ? " " + ToEN(t) : "";
public static string ToEN(this long val, double d = 20, long th = 20)
{
switch ((long)d)
{
case 20: return val >= d ? ToEN(val, 1e2) : en[val];
case 100: return val >= d ? ToEN(val, 1e3, 100) : en[val / 10 * 10] + remainder(val % 10);
default: return val >= d ? ToEN(val, d * 1e3,(long)d) : ToEN(val / th) + " " + en[th] + remainder(val % th);
}
}
