Subject: Re: [PATCH 4/5] Remove slow paths from atan2
Date: Mon, 04 Jan 2021 17:49:13 +0100	[thread overview]
Message-ID: <mwlfd8zlyu.fsf@tomate.loria.fr> (raw)
In-Reply-To: <VE1PR08MB55995DAFEA510C9BACAF0A5283D20@VE1PR08MB5599.eurprd08.prod.outlook.com> (message from Wilco Dijkstra via Libc-alpha on Mon, 4 Jan 2021 12:21:53 +0000)

       Dear Wilco,

same comments for this last patch:

- it would be nice to explain where the "Max ULP" come from, to allow
  future developers to debug the code if needed

- it would be nice to have a summary with the maximal ulp error at the
  top of the atan2() function (0.56 ULP if I'm correct)

and in addition:

- it remains one occurrence of "correctly rounded" at line 51

Best regards,
Paul
