toLocaleString() don't show zero

Question

Hello i have a question about:

Number.prototype.toLocaleString()

Trouble is that when we use "toLocaleString()" method it will not show latest maximumFractionDigits value if there was "0".

var i = 50456.40345345;
i.toLocaleString('en-US', {maximumFractionDigits: 2})
// It will return "50,456.4".
// I want to see "50,456.40".

How can i do that?

Answer 1

Use minimumFractionDigits:

var i = 50456.40345345;
i = i.toLocaleString('en-US', {maximumFractionDigits: 2, minimumFractionDigits: 2});
document.write(i);

Although you are specifying the maximumFractionDigits, the numbers don't necessarily have 2 fraction digits, so that's why you need to specify minimumFractionDigits.
