Bug ID: 16167
Summary: x86 pow raises spurious inexact exceptions for NaN
input
Product: glibc
Version: 2.18
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
x86_64 powl, and x86 powf, pow and powl, raise spurious inexact exceptions for
tests such as pow (qNaN, 2.5). According to C11 F.10, "Functions with a NaN
argument return a NaN result and raise no floating-point exception, except
where stated otherwise.", and there is no statement to override that.
