javascript - 如何在 Number to Word 转换中添加美分

问题描述

我已经有一个可以将数字转换为单词的代码，但是当我输入小数点时，它被计为“0”，我还需要在转换中添加美分。

function numberToEnglish( n ) {

    var string = n.toString(), units, tens, scales, start, end, chunks, chunksLen, chunk, ints, i, word, words, and = 'and';

    /* Remove spaces and commas */
    string = string.replace(/[,|.]/g,"");
    /* Check number if Zero? */
    if( parseInt( string ) === 0 ) {
        return 'Zero';
    }

    /* Array of units as words */
    units = [ '', 'One', 'Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine', 'Ten', 'Eleven', 'Twelve', 'Thirteen', 'Fourteen', 'Fifteen', 'Sixteen', 'Seventeen', 'Eighteen', 'Nineteen' ];

    /* Array of tens as words */
    tens = [ '', '', 'Twenty', 'Thirty', 'Forty', 'Fifty', 'Sixty', 'Seventy', 'Eighty', 'Ninety' ];

    /* Array of scales as words */
    scales = [ '', 'Thousand', 'Million', 'Billion', 'Trillion', 'Quadrillion', 'Quintillion', 'Sextillion', 'Septillion', 'Octillion', 'Nonillion', 'Decillion', 'Undecillion', 'Duodecillion', 'Tredecillion', 'Quatttuor-decillion', 'Quindecillion', 'Sexdecillion', 'Septen-decillion', 'Octodecillion', 'Novemdecillion', 'Vigintillion', 'Centillion' ];

    /* Split user arguemnt into 3 digit chunks from right to left */
    start = string.length;
    chunks = [];
    while( start > 0 ) {
        end = start;
        chunks.push( string.slice( ( start = Math.max( 0, start - 3 ) ), end ) );
    }

    /* Check if function has enough scale words to be able to stringify the user argument */
    chunksLen = chunks.length;
    if( chunksLen > scales.length ) {
        return '';
    }

    /* Stringify each integer in each chunk */
    words = [];
    for( i = 0; i < chunksLen; i++ ) {

        chunk = parseInt( chunks[i] );

        if( chunk ) {

            /* Split chunk into array of individual integers */
            ints = chunks[i].split( '' ).reverse().map( parseFloat );

            /* If tens integer is 1, i.e. 10, then add 10 to units integer */
            if( ints[1] === 1 ) {
                ints[0] += 10;
            }

            /* Add scale word if chunk is not zero and array item exists */
            if( ( word = scales[i] ) ) {
                words.push( word );
            }

            /* Add unit word if array item exists */
            if( ( word = units[ ints[0] ] ) ) {
                words.push( word );
            }

            /* Add tens word if array item exists */
            if( ( word = tens[ ints[1] ] ) ) {
                words.push( word );
            }

            /* Add 'and' string after units or tens integer if: */
            if( ints[0] || ints[1] ) {

                /* Chunk has a hundreds integer or chunk is the first of multiple chunks */
                if( ints[2] || (i + 1) > chunksLen ) {
                    words.push( and );
                }

            }

            /* Add hundreds word if array item exists */
            if( ( word = units[ ints[2] ] ) ) {
                words.push( word + ' Hundred' );
            }

        }

    }
        return words.reverse().join( ' ' );
}

当我输入 123,234.20 时，我期望输出为 123,234 20 美分，但实际输出为 12323230420
