How to manipulate a float value which starts from .somevalue to 0.somevalue in javascript/jquery? -


i have text box user enters numbers in float data type . value added previous value . when user adds float number 0.123 added fine when adds .123 throws error nan . using following code.

var labor_cost = number($("#labor_cost").val());             var other_cost = number($("#other_cost").val());             var profitvalue = number($("#profitvalue").val());             var ingcost = number($("#producttotalcost").val());             profitamount = ((ingcost+other_cost+labor_cost)*profitvalue/100);                             $("#showproposedprice").html((ingcost+other_cost+labor_cost+number(profitamount)).tofixed(2));                                                                 $("#proposedprice").val((ingcost+other_cost+labor_cost+number(profitamount)).tofixed(4));

please me how can skip or manipulate float number .123 0.123 ? thanks.

update: have tried code, , cannot reproduce error. here have done (including html), updated fiddle. can reproduce error in fiddle? if so, let me know putting in each text box. if not, compare code , see what's different:

<p>labour cost: <input type="text" id="labor_cost" /></p> <p>other cost: <input type="text" id="other_cost" /></p> <p>profit value: <input type="text" id="profitvalue" /></p> <p>product total cost: <input type="text" id="producttotalcost" /></p> <button id="submit">click</button>  <hr/> <p>show proposed price: <span id="showproposedprice"></span></p> <p>proposed price: <input type="text" id="proposedprice" /></p>  <script type="text/javascript">   $("#submit").click(function() {     var labor_cost = number($("#labor_cost").val());     var other_cost = number($("#other_cost").val());     var profitvalue = number($("#profitvalue").val());     var ingcost = number($("#producttotalcost").val());     var profitamount = ((ingcost+other_cost+labor_cost)*profitvalue/100);     $("#showproposedprice").html((ingcost+other_cost+labor_cost+number(profitamount)).tofixed(2));                                                         $("#proposedprice").val((ingcost+other_cost+labor_cost+number(profitamount)).tofixed(4));   }) </script>
