Explainer None Specification https://tc39.es/proposal-float16array Summary Adds the Float16Array typed array. Number values are rounded to IEEE fp16 when writing into Float16Array instances. Blink component Blink>JavaScript>Language <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EJavaScript%3ELanguage%22> TAG review None TAG review status Not applicable Risks Interoperability and Compatibility None. *Gecko*: Shipped/Shipping (https://www.mozilla.org/en- US/firefox/129.0/releasenotes) *WebKit*: Shipped/Shipping (https://developer.apple.com/ documentation/safari-technology-preview-release-notes/stp-release-202) *Web developers*: No signals *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? None Debuggability Debuggable like the existing typed array constructors Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? Yes Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ? Yes In test262: https://github.com/tc39/test262/pull/3849 Note that there are also a good number of WPTs that check that Float16Arrays are supported in web APIs. For example, https://wpt.fyi/results/WebCryptoAPI/getRandomValues.any.html?label=experimental&label=master&aligned or https://wpt.fyi/results/fetch/api/basic/request-headers.any.html?label=experimental&label=master&aligned . Canary with experimental web platform features is currently failing these. Can you confirm that shipping Float16Array per this Intent will be enough to make these pass? Or would there be additional work necessary? Flag name on about://flags --js-float16array Finch feature name V8Flag_js_float16array Requires code in //chrome?

Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
