วิธีการแปลงตัวเลขเป็นคำใน java


132

ขณะนี้เรามีกลไกคร่าวๆในการแปลงตัวเลขเป็นคำ (เช่นการใช้อาร์เรย์แบบคงที่) และขึ้นอยู่กับขนาดของตัวเลขที่แปลเป็นข้อความภาษาอังกฤษ แต่เรากำลังประสบปัญหาสำหรับตัวเลขที่มีขนาดใหญ่มาก

10183 = Ten thousand one hundred eighty three
90 = Ninety
5888 = Five thousand eight hundred eighty eight

มีฟังก์ชันที่ใช้งานง่ายในห้องสมุดคณิตศาสตร์ที่ฉันสามารถใช้เพื่อจุดประสงค์นี้ได้หรือไม่?

นี่คือรหัสฉันไม่คิดว่าจะมีวิธีใดใน SE

โดยทั่วไปจะแปลงตัวเลขเป็นสตริงและแยกวิเคราะห์สตริงและเชื่อมโยงกับน้ำหนัก

ตัวอย่างเช่น

1000

1ได้รับการปฏิบัติเป็นพันตำแหน่งและ1ได้รับการแมป"one"และพันเนื่องจากตำแหน่ง

คุณสามารถจัดการการแปลง "ดอลลาร์และเซ็นต์" ได้โดยเรียกวิธีการ "แปลง" สองครั้ง

String phrase = "12345.67" ;
Float num = new Float( phrase ) ;
int dollars = (int)Math.floor( num ) ;
int cent = (int)Math.floor( ( num - dollars ) * 100.0f ) ;

String s = "$ " + EnglishNumberToWords.convert( dollars ) + " and "
           + EnglishNumberToWords.convert( cent ) + " cents" ;

'JSP' means :
J : the Julian format.

เนื่องจากคุณไม่สามารถมีอัลกอริทึมทั่วไปสำหรับทุกภาษาจึงไม่มี คุณต้องใช้อัลกอริทึมของคุณเองสำหรับทุกภาษาที่คุณสนับสนุน

** แก้ไข **

ฉันเล่นไปเรื่อย ๆ จนได้คลาสนี้ ไม่สามารถแสดงได้Long.MIN_VALUEเนื่องจากข้อ จำกัด ของบิต ... แต่ฉันคิดว่ามันสามารถแก้ไขและเปลี่ยนlongประเภทค่าdoubleเป็นทศนิยมหรือตัวเลขที่ใหญ่กว่าได้สามารถแสดงตัวเลขใดก็ได้มากถึง 66 หลักและ 26 ทศนิยมโดยใช้การแสดงสตริงของตัวเลข คุณสามารถเพิ่มScaleUnitจำนวนทศนิยมได้มากขึ้น ...

@ Don Roby - AFAIK นั่นคือความกังวลในประวัติศาสตร์เท่านั้น คนอังกฤษส่วนใหญ่ใช้ภาษาอังกฤษแบบอเมริกันในปัจจุบัน (แน่นอนว่ามีคนประหลาดบางคนที่เขียนจดหมาย (ด้วยหมึกสีเขียว) ถึง The Times เกี่ยวกับเรื่องแบบนี้ แต่พวกเขาอาจจะไม่สังเกตเห็นเนื่องจากปฏิเสธที่จะเรียนรู้การใช้คอมพิวเตอร์ :-))

ICU4Jมีการสนับสนุนการสะกดตัวเลขที่ดี ไฟล์ที่มี "กฎ" สามารถแก้ไขได้อย่างง่ายดายและไม่มีปัญหาในการเพิ่มภาษาอื่น ๆ (เราทำเช่นสำหรับโปแลนด์และรัสเซีย)


ข้อมูลของ ICU4J มาจาก CLDR unicode.org/cldrและรองรับภาษาโปแลนด์และรัสเซียแล้ว unicode.org/repos/cldr/trunk/common/rbnfคุณยื่นตั๋วหากพบปัญหาเกี่ยวกับกฎที่มีอยู่หรือไม่

ไม่ แต่เราทำสิ่งนี้เมื่อหลายปีก่อนและถ้าจำไม่ผิดเราต้องการบางสิ่งเพิ่มเติม แต่น่ารู้!

มีเหตุผลไหมที่คำตอบเหล่านี้มีไวยากรณ์ที่ไม่ดี? "1234" ควรจะเป็น "หนึ่งพันสองร้อยและสามสิบ-โฟร์" ฉันไม่รู้ภาษาอังกฤษด้านการธนาคารหรือไม่

ในโพสต์นี้ฉันเพิ่งอัปเดตรหัสของ Yanick Rochon ฉันต้องทำให้มันใช้การได้กับรุ่นล่างของ Java 1.6 และฉันได้รับผลลัพธ์สำหรับ1.00 = หนึ่งร้อย ดังนั้นฉันจึงอัปเดตรหัส ใหม่ฉันจะได้รับผลลัพธ์สำหรับ1.00 = หนึ่งและเป็นศูนย์การร้อย

ฉันไม่ควรทำอะไร เพิ่มคำตอบใหม่หรือแก้ไขโพสต์นั้น เนื่องจากคำตอบอยู่ในอันดับสูงดังนั้นฉันจึงได้โพสต์ใหม่พร้อมอัปเดตโค้ด ฉันเพิ่งเปลี่ยนสองสิ่งนี้ได้กล่าวไว้ข้างต้น

คุณสามารถใช้ RuleBasedNumberFormat ตัวอย่างเช่นผลลัพธ์จะให้คุณNinety

ULocale locale = new ULocale(Locale.US);  //us english
Double d = Double.parseDouble(90);
NumberFormat formatter = new RuleBasedNumberFormat(locale, RuleBasedNumberFormat.SPELLOUT);
String result = formatter.format(d);

คุณอาจไม่ต้องการสิ่งนี้อีกต่อไป แต่ฉันเพิ่งเขียนคลาส java เพื่อทำสิ่งนี้ เห็นได้ชัดว่า Yanick Rochon ทำสิ่งที่คล้ายกัน มันจะแปลงตัวเลขได้ถึง 999 Novemdecillion (999 * 10 ^ 60) มันสามารถทำได้มากกว่านี้ถ้าฉันรู้ว่าเกิดอะไรขึ้นหลังจาก Novemdecillion แต่ฉันยินดีที่จะเดิมพันว่ามันไม่จำเป็น เพียงป้อนตัวเลขเป็นสตริงในหน่วยเซ็นต์ ผลลัพธ์ยังถูกต้องตามหลักไวยากรณ์

ฉันได้พัฒนาคอมโพเนนต์ Java เพื่อแปลงตัวเลขที่กำหนดเป็นคำ สิ่งที่คุณต้องทำมีเพียงแค่คัดลอกทั้งคลาสจากโปรแกรม Java เพื่อแปลงตัวเลขเป็นคำและวางในโปรเจ็กต์ของคุณ

เพียงแค่เรียกใช้เช่นด้านล่าง

Words w = Words.getInstance(1234567);
System.out.println(w.getNumberInWords());

โปรแกรมของฉันรองรับมากถึง 10 ล้าน หากต้องการคุณยังสามารถขยายได้ ด้านล่างผลลัพธ์ตัวอย่าง

2345223 = Twenty Three Lakh Fourty Five Thousand Two Hundred Twenty Three
9999999 = Ninety Nine Lakh Ninety Nine Thousand Nine Hundred Ninety Nine
199 = One Hundred Ninety Nine
10 = Ten

ขอบคุณ

คุณสามารถใช้ICU4Jเพียงแค่ต้องเพิ่มรายการ POM และรหัสอยู่ด้านล่างสำหรับหมายเลขประเทศและภาษาใด ๆ

รายการ POM

     <dependency>
        <groupId>com.ibm.icu</groupId>
        <artifactId>icu4j</artifactId>
        <version>64.2</version>
    </dependency>

รหัสคือ

public class TranslateNumberToWord {

/**
 * Translate
 * 
 * @param ctryCd
 * @param lang
 * @param reqStr
 * @param fractionUnitName
 * @return
 */
public static String translate(String ctryCd, String lang, String reqStr, String fractionUnitName) {
    StringBuffer result = new StringBuffer();

    Locale locale = new Locale(lang, ctryCd);
    Currency crncy = Currency.getInstance(locale);

    String inputArr[] = StringUtils.split(new BigDecimal(reqStr).abs().toPlainString(), ".");
    RuleBasedNumberFormat rule = new RuleBasedNumberFormat(locale, RuleBasedNumberFormat.SPELLOUT);

    int i = 0;
    for (String input : inputArr) {
        CurrencyAmount crncyAmt = new CurrencyAmount(new BigDecimal(input), crncy);
        if (i++ == 0) {
            result.append(rule.format(crncyAmt)).append(" " + crncy.getDisplayName() + " and ");
        } else {
            result.append(rule.format(crncyAmt)).append(" " + fractionUnitName + " ");
        }
    }
    return result.toString();
}

public static void main(String[] args) {
    String ctryCd = "US";
    String lang = "en";
    String input = "95.17";

    String result = translate(ctryCd, lang, input, "Cents");
    System.out.println("Input: " + input + " result: " + result);
}}

ทดสอบด้วยตัวเลขที่ค่อนข้างใหญ่และผลลัพธ์จะเป็น

Input: 95.17 result: ninety-five US Dollar and seventeen Cents
Input: 999999999999999999.99 result: nine hundred ninety-nine quadrillion nine hundred ninety-nine trillion nine hundred ninety-nine billion nine hundred ninety-nine million nine hundred ninety-nine thousand nine hundred ninety-nine US Dollar and ninety-nine Cents 

ฉันได้พัฒนา REST Api เพื่อรองรับ Number to Words สำหรับภาษาใด ๆ ใช้งานฟรีทดลองใช้งาน49.206.25.208:18080/api/v1/generate/…

String numberInWords = NumberInWords.convertNumberToWords(27546); //twenty seven thousand and five hundred forty six

มันเป็นสิ่งสำคัญที่จะรู้ว่าชั้นนี้เป็นเพียงความสามารถในการแปลงชนิดข้อมูล int
