Subject: [musl] Obsolete comment in powl, and (s)NaN handling ?
Date: Mon, 05 Aug 2024 14:22:34 +0200	[thread overview]
Message-ID: <9ea8df217179a1c6c7bc0bd0d7001721@ens.psl.eu> (raw)

Hello,

Currently, src/math/powl.c line 66 states that powl(x, y)
returns 0 when x < 0 and y not an integer. However, lines 290-291

> if (iyflg == 0)
>     return (x - x) / (x - x); /* (x<0)**(non-int) is NaN */

precisely ensure this is not the case. Both these excerpts come
from the original commit. Maybe line 66 should be deleted/corrected ?

Deviating a bit, are there plans for supporting signalling NaNs in Musl 
?

Thanks in advance,
Sélène
