Subject: Remove sqrt ulps for MIPS
Date: Thu, 31 May 2012 21:31:00 -0000 [thread overview]
Message-ID: <Pine.LNX.4.64.1205312128590.19630@digraph.polyomino.org.uk> (raw)
Now that M_SQRT2l has been adjusted so it rounds to 113 bits to the same
value as the exact square root of 2 does, I've applied this patch to the
MIPS libm-test-ulps to remove ulps for sqrt. The same should be done for
alpha (and in libc, sparc and s390). If you find ulps for sqrt appearing
when you regenerate ulps, they should be investigated further since sqrt
is meant always to give a correctly rounded result.
