Adding a plus sign before positive numbers using NumberSymbol in Angular

Issue

I am displaying a number the following way:

{{product.weight}}

I would like to make it so if the number is positive it shows with a + sign.

I see documentation on something called NumberSymbol which is an enum but not sure how to properly use it with a pipe:

https://angular.io/api/common/NumberSymbol

Solution

Use this:

{{product.weight > 0 ? '+' + product.weight : product.weight}}
