You can use plain Javascript:

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

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

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

You can do it in plain old Javascript:

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

You could also look into the Math object. There might be a rounding function in it.
