Currency pipe, digits info with either 0 or 2 decimals (but not 1)

🚀 feature request

Relevant Package

This feature request is for @angular/common

Description

In many use cases where showing currency, it looks better to not show any decimals when there aren't any to show. So "€100" instead of "€100.00". However when the price is 99.99 you do want to show the decimals. What you don't want is when the price is 99.90, to have it shown as 99.9.

This means that none of the number formats "1,0", "1.2" or "1.0-2" have the desired effect.

Describe the solution you'd like

To be able to specify 2 options for decimals, for instance: "1.0|2".

So that:

• 1.0 | currency : 'EUR' : 'symbol' : '1.0|2' -> €1
• 1.1 | currency : 'EUR' : 'symbol' : '1.0|2' -> €1.10
• 1.11 | currency : 'EUR' : 'symbol' : '1.0|2' -> €1.11

Hello, I'm sorry but we will not implement this feature request as it is very specific to your personal preference.
That being said, it's very easy to create your own currency pipe that does what you want.
You can copy the code of the existing currency pipe: https://github.com/angular/angular/blob/master/packages/common/src/pipes/number_pipe.ts#L136-L224 and then change it to post process numbers exactly the way you want.

I know this is closed but @WanderG:

Create your own pipe that injects the currency pipe. In your transform, test the value to see if value % 1 > 0. If so, use the currencyPipe's transform with it's regular digitsInfo format (the 1.2-2). If not, pass in your 1.0-0 format.

This feature does not feel like a generic feature because the currencyPipe's transform follows the ISO 4217 format (read more here) which requires the decimal numbers (or minor units) to be shown.
