Intl.NumberFormat either 0 or two fraction digits

rated 0 times [ 156] [ 7] / answers: 1 / hits: 63715 / 6 Years ago, mon, april 9, 2018, 12:00:00

My formatter looks like this

const formatter = new Intl.NumberFormat('en-NZ', {

  style: 'currency',

  currency: 'NZD',

  minimumFractionDigits: 2,

});

How can I adjust this so that whole numbers have 0 fraction digits

formatter.format(4); // want output $4

whilst fractions always show two digits?

formatter.format(4.1); // want output $4.10

You could try something like this:

formatter.format(amount).replace(/D00$/, '');

Update:

In response to the many-months-later comment by @Marek, the above regex already handles differing decimal symbols (either . or ,), but it's true that it doesn't handle trailing currency symbols. That can be fixed this way:

formatter.format(amount).replace(/D00(?=D*$)/, '');
