Subject: [PATCH 0/4] Fix huge error for pow detected by Paul Zimmermann
Date: Wed, 12 Apr 2023 17:34:41 +0200 [thread overview]
Message-ID: <20230412153445.161047-1-andoni.arregui@gtd-gmbh.de> (raw)
This patch series fixes in pow the huge error detected by Paul
Zimmermann where x is negative and y is a large odd integer.
There is also an accuracy fix for cases where x is close to 1 and y is
large.
Andoni Arregi (4):
Fix missing sign for overflow/underflow where x is negative and y is
large odd integer
Fix x close to 1, y between 2^31 and 2^64
Compare j as unsigned
Replace always true if with else
