Javascript：值没有正确显示浮动

Question

我有一个角度代码，可以从谷歌财务中获取数据。但是，如果存在代表数百万和数千的M或K，它可以正确获取 vo 和 avvo 的数据。如果没有它，则无法正确显示该值。

如何正确处理这两种情况？

示例数据如下。第一个有浮点数据，第二个有M，我认为是字符串。我可以正确显示字符串但浮动不正确。它将显示为N / A和avvo为2.000。我想在数据中显示确切的值

// [
{
"id": "549805688244420"
,"t" : "AZG"
,"vo" : "0.00"
,"avvo" : "2,087.00"

}
]

和

// [
{
"id": "381558643124633"
,"t" : "U11"
,"vo" : "1.34M"
,"avvo" : "2.47M"

}
]

以下是我的代码：

angular.module('myapp.factories').factory('$stockDataFactory',
  ['$q', '$filter', '$webServicesFactory',
    function ($q, $filter, $webServicesFactory) {
      return {
        getStockDetails: function (stock) {
          var deferred = $q.defer();

          $webServicesFactory.getNotParsed(
            "https://www.google.com/finance/info",
            {},
            {
              infotype: "infoquoteall",
              q: stock.market+":"+stock.symbol
            }
          ).then(
            function success(response) {
              response = JSON.parse("["+response.replace(/\r?\n|\r/g, ' ').split('[').splice(1,1)[0]);
              stock = response[0];
        var formatedData = {
                  volume: stock.vo,
                  averageDailyVolume: stock.avvo
           };

HTML：

  <div class="row row-center">
    <div class="col boldText">Volume: </div>
    <div class="col col-21">{{stock.volume || 'N/A'}}</div>
    <div class="col boldText">Avg. Vol: </div>
    <div class="col col-21">{{(stock.averageDailyVolume | shrinkNumber: 2) || 'N/A'}}</div>
  </div>

js中的shrinkNumber

angular.module('chaishen.factories').filter("shrinkNumber", function($filter) {
  return function(number, fractionSize) {

    if(number === null) return null;
    if(number === 0) return "0.000";

    // default number of decimals for values >1000 or <-1000 if not set in view
    if(!fractionSize || fractionSize < 0)
      fractionSize = 1;

    var abs = Math.abs(number);
    var rounder = Math.pow(10,fractionSize);
    var isNegative = number < 0;
    var key = '';
    var powers = [
      {key: "Q", value: Math.pow(10,15)},
      {key: "T", value: Math.pow(10,12)},
      {key: "B", value: Math.pow(10,9)},
      {key: "M", value: Math.pow(10,6)},
      {key: "K", value: 1000}
    ];

    for(var i = 0; i < powers.length; i++) {

      var reduced = abs / powers[i].value;

      //reduced = Math.round(reduced * rounder) / rounder;
      reduced = Math.round(abs * rounder) / rounder;

      if(reduced >= 1){
        abs = reduced;
        key = powers[i].key;
        break;
      }
    }

    if(number >= 1000) {
      //return abs + key;
      return abs;
    }
    else if(number <= -1000) {
      //return '-' + abs + key;
      return '-' + abs;
    }
    else {
      //return $filter('number')(((isNegative ? '-' : '') + abs + key), 3);
      return $filter('number')(((isNegative ? '-' : '') + abs), 3);
    }
  };
});
