Javascript multiplication

Question

I'm using Google Chrome.

<html>
    <head>
        <script>
            function DoThis()
            {
                var value = 1.005;
                var multiplied = value * 100;
                alert(multiplied);
            }
        </script>
    </head>
    <body onload="DoThis();">

    </body>
</html>

multiplied ends up coming out as 100.49999999 instead of 100.5

Anyone have an explanation?

All numbers in Javascript are stored as floats. You're seeing one of the limittions of float arithmetic.
