ii)String to Float
To convert a value from string to float, we have to use the function or method parseFloat().
The parseFloat() function parses a string and returns a floating point number.
Example
<html>
<body>
<script type="text/javascript">
<body>
<script type="text/javascript">
document.write(parseFloat ("35.49") + "<br />");
document.write(parseFloat ("35.00000000")+ "<br />");
document.write(parseFloat ("35") + "<br />");
document.write(parseFloat ("0x35")+ "<br />");
document.write(parseFloat ("035")+ "<br />");
document.write(parseFloat ("Hello")+ "<br />");
</script>
</body>
