| Summary | 0007915: pass correct currency_fraction_digits to wallet UIs | ||||
| Description | This is the desired number of digits amounts in this currency should typically be rendered in. As per castle discussion with Florian and Marc. The parameter is already supported in the latest exchange (defaults to 0). | ||||

| duplicate of | 0008184 | assigned | Florian Dold | wallet-core should provide real currency specification data instead of mock data [estimate: 6h] |
|
|
In order for UIs to validate cached info about currencies, wallet-core should also emit a "currency-info-change" notification whenever currency info changes. |
|
|
Please set the default for numFractionalDigits to 2 (€, $, most other currencies), as 0 is only used by ¥. (Some arabic currencies use 3 - I don't know any "global" currency using other values than 0, 2 or 3) Set the default for numTinyDigits to 0. |
|
|
4a64d721..32659fe7 sets the default to 2 (in the exchange). Note that numTinyDigits should not have a default at all, it MUST be "computed" by the wallet based on the actual denominations offered by the exchange. |
|
|
"computed by the wallet" - does this mean wallet-core does this when it adds an Exchange, and whenever denominations change, but the result is rather a constant for the frontend (cached, with notification from wallet-core when changed)? Or does the frontend need to compute this for every transaction? |
|
|
Wallet-core should (re)compute it whenever it gets a new /keys response. (count maximum number of fractional digits encountered in all denominations). |
|
|
if the currency is official then we MUST use ISO 4217 table https://en.wikipedia.org/wiki/ISO_4217 what is the purpose or the user case for numTinyDigits ? |
|
|
Use case for numTinyDigits is to be able to specify e.g. fractions of a cent like gas filling stations do (1,23⁴ or 0.78⁹). |
|
|
This will be addressed by not mocking the currency specification anymore (See #8183). |
