Answer 1

Please look at this code below:

var value ="1231244"
var lasttwovalue = value % 100;
var firstValue= parseInt(value.slice(0,-2))
if(lasttwovalue >50)
{
   lasttwovalue = '00';
   firstValue = firstValue + parseInt(1)
}
console.log('$'+ firstValue.toLocaleString() + '.' + lasttwovalue)

//result is $12,313.00 if value is 1231255
//result is $12,312.44 if value is 1231244
