Print the value of the number (int) spelled out

Question

Is there an out-of-the-box way to expose int in C #? For example, if I have:

int a = 53; 

I want to print:

 "fifty three" 

not

 "53" 

If not, does anyone have examples of how to do this?

Thanks!

Answer 1

You must write this code yourself. If I were to guess, I would say that it is not within the scope, because it would be impossible to localize (there are much more than just the names of numbers: word order, hyphen, etc.).

This brings back memories because it was a task from my first college programming course, so it shouldn't be too hard for you to write it in English only.

Here is the code to convert numbers to words.

 using System; namespace WpfApplication1 { public class NumberToEnglish { public String changeNumericToWords(double numb) { String num = numb.ToString(); return changeToWords(num, false); } public String changeCurrencyToWords(String numb) { return changeToWords(numb, true); } public String changeNumericToWords(String numb) { return changeToWords(numb, false); } public String changeCurrencyToWords(double numb) { return changeToWords(numb.ToString(), true); } private String changeToWords(String numb, bool isCurrency) { String val = "", wholeNo = numb, points = "", andStr = "", pointStr=""; String endStr = (isCurrency) ? ("Only") : (""); try { int decimalPlace = numb.IndexOf("."); if (decimalPlace > 0) { wholeNo = numb.Substring(0, decimalPlace); points = numb.Substring(decimalPlace+1); if (Convert.ToInt32(points) > 0) { andStr = (isCurrency)?("and"):("point");// just to separate whole numbers from > points/cents endStr = (isCurrency) ? ("Cents "+endStr) : (""); pointStr = translateCents(points); } } val = String.Format("{0} {1}{2} {3}",translateWholeNumber(wholeNo).Trim(),andStr,pointStr,endStr); } catch { ;} return val; } private String translateWholeNumber(String number) { string word = ""; try { bool beginsZero = false;//tests for 0XX bool isDone = false;//test if already translated double dblAmt = (Convert.ToDouble(number)); //if ((dblAmt > 0) && number.StartsWith("0")) if (dblAmt > 0) {//test for zero or digit zero in a nuemric beginsZero = number.StartsWith("0"); int numDigits = number.Length; int pos = 0;//store digit grouping String place = "";//digit grouping name:hundres,thousand,etc... switch (numDigits) { case 1://ones' range word = ones(number); isDone = true; break; case 2://tens' range word = tens(number); isDone = true; break; case 3://hundreds' range pos = (numDigits % 3) + 1; place = " Hundred "; break; case 4://thousands' range case 5: case 6: pos = (numDigits % 4) + 1; place = " Thousand "; break; case 7://millions' range case 8: case 9: pos = (numDigits % 7) + 1; place = " Million "; break; case 10://Billions range pos = (numDigits % 10) + 1; place = " Billion "; break; //add extra case options for anything above Billion... default: isDone = true; break; } if (!isDone) {//if transalation is not done, continue...(Recursion comes in now!!) word = translateWholeNumber(number.Substring(0, pos)) + place + translateWholeNumber(number.Substring(pos)); //check for trailing zeros if (beginsZero) word = " and " + word.Trim(); } //ignore digit grouping names if (word.Trim().Equals(place.Trim())) word = ""; } } catch { ;} return word.Trim(); } private String tens(String digit) { int digt = Convert.ToInt32(digit); String name = null; switch (digt) { case 10: name = "Ten"; break; case 11: name = "Eleven"; break; case 12: name = "Twelve"; break; case 13: name = "Thirteen"; break; case 14: name = "Fourteen"; break; case 15: name = "Fifteen"; break; case 16: name = "Sixteen"; break; case 17: name = "Seventeen"; break; case 18: name = "Eighteen"; break; case 19: name = "Nineteen"; break; case 20: name = "Twenty"; break; case 30: name = "Thirty"; break; case 40: name = "Fourty"; break; case 50: name = "Fifty"; break; case 60: name = "Sixty"; break; case 70: name = "Seventy"; break; case 80: name = "Eighty"; break; case 90: name = "Ninety"; break; default: if (digt > 0) { name = tens(digit.Substring(0, 1) + "0") + "" + ones(digit.Substring(1)); } break; } return name; } private String ones(String digit) { int digt = Convert.ToInt32(digit); String name = ""; switch (digt) { case 1: name = "One"; break; case 2: name = "Two"; break; case 3: name = "Three"; break; case 4: name = "Four"; break; case 5: name = "Five"; break; case 6: name = "Six"; break; case 7: name = "Seven"; break; case 8: name = "Eight"; break; case 9: name = "Nine"; break; } return name; } private String translateCents(String cents) { String cts = "", digit = "", engOne = ""; for (int i = 0; i < cents.Length; i++) { digit = cents[i].ToString(); if (digit.Equals("0")) { engOne = "Zero"; } else { engOne = ones(digit); } cts += " " + engOne; } return cts; } } } 

create a class file in your project, copy this code to the class file. Changing the namespace in the project Namespace.

create an object of this class like this

 NumberToEnglish objnumber = new NumberToEnglish(); 

and with objnumber.changeNumericToWords(100);

with this function you will get the number in a word.

It uses an instance method, but you can make these methods static .

Answer 3

Here's an extra way, just for kicks.

 public static class NumericSpelling { private const long Quadrillion = Trillion * 1000; private const long Trillion = Billion * 1000; private const long Billion = Million * 1000; private const long Million = Thousand * 1000; private const long Thousand = Hundred * 10; private const long Hundred = 100; public static string ToVerbal(this int value) { return ToVerbal((long)value); } public static string ToVerbal(this long value) { if (value == 0) return "zero"; if (value < 0) { return "negative " + ToVerbal(Math.Abs(value)); } System.Text.StringBuilder builder = new StringBuilder(); int unit = 0; if (value >= Quadrillion) { unit = (int)(value / Quadrillion); value -= unit * Quadrillion; builder.AppendFormat("{0}{1} quadrillion", builder.Length > 0 ? ", " : string.Empty, ToVerbal(unit)); } if (value >= Trillion) { unit = (int)(value / Trillion); value -= unit * Trillion; builder.AppendFormat("{0}{1} trillion", builder.Length > 0 ? ", " : string.Empty, ToVerbal(unit)); } if (value >= Billion) { unit = (int)(value / Billion); value -= unit * Billion; builder.AppendFormat("{0}{1} billion", builder.Length > 0 ? ", " : string.Empty, ToVerbal(unit)); } if (value >= Million) { unit = (int)(value / Million); value -= unit * Million; builder.AppendFormat("{0}{1} million", builder.Length > 0 ? ", " : string.Empty, ToVerbal(unit)); } if (value >= Thousand) { unit = (int)(value / Thousand); value -= unit * Thousand; builder.AppendFormat("{0}{1} thousand", builder.Length > 0 ? ", " : string.Empty, ToVerbal(unit)); } if (value >= Hundred) { unit = (int)(value / Hundred); value -= unit * Hundred; builder.AppendFormat("{0}{1} hundred", builder.Length > 0 ? ", " : string.Empty, ToVerbal(unit)); } if (builder.Length > 0 && value > 0) builder.AppendFormat(" and"); if (value >= 90) { value -= 90; builder.AppendFormat("{0}ninety", builder.Length > 0 ? " " : string.Empty); } if (value >= 80) { value -= 80; builder.AppendFormat("{0}eighty", builder.Length > 0 ?

 ten thousand, four hundred and forty seven ten trillion, five hundred and seventy six billion, seven hundred and forty nine million, three hundred and twenty three thousand, four hundred and seventy five zero negative one thousand and ninety five one hundred one hundred and two ten thousand and four one hundred thousand and twenty five 

Answer 4

If all else fails, ask Bill Gates and his team. This should help you get started.

Answer 6

Yes, there is a way to do this. International components for Unicode has a RuleBasedNumberFormatter with the "spell" option. It even supports full localization.

The only obstacle is that it is available only in C, C ++ and Java. There is an initiative in the icu.net project (both for the .NET Framework and the .NET Standard 1.6), but this function and many others have not yet been ported. However, the contribution can solve this quite well.

There is also a tool that should automatically generate a C # cover library around the ICU4C library, but I don't know, I tried.

Other options are available for other programming languages.
