Answer 2

You can use simple Javascript:

var n = 3.23214215
var fixed = n.toFixed(1)

Answer 3

You don't need jquery, plain old javascript does the trick:

var chopped = Math.floor(full_length * 10.0) / 10.0;

Answer 4

You can do this in simple Javascript:

var f = 3.23214215;
f *= 10;
var i = parseInt(f);
f = i / 10;

You can also explore the Math object. It may have a rounding function.
