This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. NumberFormat.currency formats with the three-letter ISO code unless simpleCurrency or an explicit symbol is used.
  2. NumberFormat.simpleCurrency parsing accepts both a symbol-prefixed value and the same localized number without its currency symbol.
  3. NumberFormat.simpleCurrency for JPY uses zero decimal places while currency with only an explicit yen symbol inherits the locale's decimal digits.
  4. NumberFormat.percentPattern multiplies by 100 and its locale pattern displays no fraction digits by default, while decimalPercentPattern can preserve them.
  5. NumberFormat.compactCurrency uses an ISO code while compactSimpleCurrency uses the currency symbol.
