Java Script represents numbers in the form of IEEE-754 doubles. This form of representation provides accuracy upto 14-15 significant digits. They represent fractions but not the decimal numbers to an extent. To perform explicit numeric conversion you can use Number constructor.

<script type="text/javascript">
function add(){
var a = "55";
var b = "45";
alert( Number(a) + Number(b) );
}
</script>
