Javascript will convert types automatically if you just use them in a context where that needs to happen. For example, you can just add an empty string to your float and the result will be a string:

var x = 3.14952;
var y = x + '';
window.alert( typeof x ); // number
window.alert( typeof y ); // string

You can also do explicit casting, but it's usually not necessary.

ParseFloat (and also parseInt) will skip any leading non-number characters btw, such as US$ e.g.
