use .toFixed(int):

var amount = 100;
document.querySelector('pre').innerHTML = parseFloat(amount).toFixed(1);

<pre></pre>

alert(amount.toFixed(2));  // output: 100.00
alert(amount.toFixed(3));  // output: 100.000

var amount = 100;
alert(amount);  // output: 100
alert(amount.toFixed(1));  // output: 100.0
alert(amount.toFixed(2));  // output: 100.00
alert(amount.toFixed(3));  // output: 100.000

**number.toFixed(x)**

where number is what you intend to convert to double, and X is the precision you want to set.
