Subject: [Bug 214815] New: pow(3): underflow result can be -0.0
Date: Mon, 25 Oct 2021 22:33:48 +0000 [thread overview]
Message-ID: <bug-214815-11311@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=214815
Bug ID: 214815
Summary: pow(3): underflow result can be -0.0
Product: Documentation
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: low
Priority: P1
Component: man-pages
Assignee: documentation_man-pages@kernel-bugs.osdl.org
Reporter: mwelinder@gmail.com
Regression: No
The pow(3) man pages as found here:
https://man7.org/linux/man-pages/man3/pow.3.html says...
"If result underflows, and is not representable, a range error occurs, and 0.0
is returned."
That fails to take signs into account. pow(-1e-100,5) produces -0.0, not 0.0
Suggested wording: "... and 0.0 with the appropriate sign is returned."
