[libc-commits] [PATCH] D115408: [libc] Implement correctly rounded logf based on RLIBM library.

[Paul Zimmermann via Phabricator via libc-commits]

zimmermann6 added a comment.

Do you know the cost in latency/throughput of the switch() with the 21 exceptional cases? Another way would be to perform a rounding test once the approximation of log has been computed, and go in the switch only if the test fails (which would happen very rarely).
