Re: [w3c/browser-payment-api] Should the amount be in decimal or cents? (#204)

Thank you for the suggestion.

#### Cents vs Dollars
We are not using cents because we want to be compatible with such standards as [ISO 20022](https://www.iso20022.org/standardsrepository/public/wqt/Description/mx/dico/datatypes/_YX4O9tp-Ed-ak6NoX_4Aeg_-836081793), which allows up to 5 fractional digits. We can express $50.001 as `"value": "50.001"`, but your proposal would result in `"value": "5000.1"`. I think the latter would be confusing to developers.

#### Commas vs Dollars
We want the developer to write code once and have it work in all localities. So, the website developer would write `"value": "55.00"` always with periods, but the user agent (e.g. browser) will format this into user locale. For example, US locale will show "55.00", but DE locale will show "55,00".
