Bug ID: 16348
Summary: x86 / x86_64 expl spurious underflows
Product: glibc
Version: 2.19
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
The x86 / x86_64 expl implementations produce spurious underflow exceptions for
arguments very close to 0 (in which case the result is very close to 1). E.g.,
expl (0x1p-16384L) produces such exceptions for both x86_64 and x86.
