Subject: large powf error
Date: Tue, 15 Dec 2020 12:41:56 +0100 [thread overview]
Message-ID: <mwlfdzuwhn.fsf@tomate.loria.fr> (raw)
Hi,
I confirm the patch from Fabian [1] fixes the large error for powf.
With that patch applied on top of Newlib 4.0.0, the largest error I get
so far is about 160 ulps after a quick test:
x,y=0x1.f4fcdap-1,0x1.ee1fe4p+11 [1.61e+02] 160.483
Best regards,
Paul
