This patch is intended to cover only one aspect of the proposal for ECMA402: the "grouping enum" feature. It also includes coverage for the formatting option as already defined by the latest version of ECMA402.

description: Tests that the option useGrouping is processed correctly.
|
|
info: |
|
|
The "Intl.NumberFormat v3" proposal contradicts the behavior required by the
|
|
latest revision of ECMA402. Likewise, this test contradicts
|
|
test-option-useGrouping.js. Until the proposal is included in a published
|
|
standard (when the tests' discrepancies can be resolved), implementations
|
|
should only expect to pass one of these two tests.
|
|
features: [Intl.NumberFormat-v3]
