weired results when i Sum numeric values inside my javaScript (JSLINK file)

I am writing the following Javascript (JSLINK) to show the
Sum of a numeric value, as
follow:-

var
            _totalValue1 = 0.0;
var _totalColumn = 27; // Specify total number of columns
            in list view.
var _columnIndex1 = 14; // Specify the index of the column where
            you want to display sum values. (i.e. index for first column =
            1)
alert(101010);
function myCSRRendering1 ()
            {

 var calculatedFieldCtx = {}; 


            calculatedFieldCtx.Templates = {};



            calculatedFieldCtx.Templates.Fields = {
 "Yearof2017MLC": {
 "View":
            CalculatedFieldViewTemplate1
 }
 };

            SPClientTemplates.TemplateManager.RegisterTemplateOverrides(calculatedFieldCtx);
            
 calculatedFieldCtx.OnPostRender = [];

            calculatedFieldCtx.OnPostRender.push(function()
 { 
 // Specify id
            of the list view table for which you want to display sum values. 


            var HTMLTableElement =
            document.getElementById("{B3D883A5-6962-47FD-BDEF-BB83FF4C78EA}-{C86BA145-8C22-47E8-938C-11B8C7F855C3}");


            var tbodyElement = document.createElement('thead');
 tbodyElement.id =
            "customAggWPQ";

 var trElement =
            document.createElement('tr');

 var tdElement;
 for(var i
            = 1; i <= _totalColumn; i++) {
 tdElement =
            document.createElement('th');

 tdElement.id = "tdElement" +
            i;
 if( i == _columnIndex1) {
 tdElement.innerHTML = "Sum=
            " + numberFormat(_totalValue1) + "";
 }

            trElement.appendChild(tdElement);
 }


            tbodyElement.appendChild(trElement);

            if(document.getElementById("customAggWPQ") == null) {

            HTMLTableElement.insertBefore(tbodyElement,HTMLTableElement.firstChild.nextSibling);


            }
 else {
 document.getElementById("tdElement" +
            _columnIndex1).innerHTML = "Sum= " + numberFormat(_totalValue1) +
            "";
 }
 _totalValue1 = 0.0;

            })


            SPClientTemplates.TemplateManager.RegisterTemplateOverrides(

            calculatedFieldCtx

            );


};


function
            CalculatedFieldViewTemplate1(ctx) {
            

if(ctx.CurrentItem.Yearof2017MLC != "" ){
_totalValue1
            += parseFloat((ctx.CurrentItem.Yearof2017MLC).replace(',', ''));
return
            ctx.CurrentItem.Yearof2017MLC;
}


            else
{
 return
            0;
}


}
// register for MDS enabled
            sites
RegisterModuleInit('http://arqcvsps01/offices/resources/t10.js',
            myCSRRendering1);


// fallback for non-MDS enabled
            sites
myCSRRendering1(); 
var numberFormat = function(number)
            {


 return
            number;
};

now
the result i should get is 97.4456 while the JSLINK is showing
97.44560000000001.. here is my
table:-
