Bug ID: 18049
Summary: [i386] atanhl spurious underflows
Product: glibc
Version: 2.21
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
Host: i?86-*-*
The i386 implementation of atanhl computes twice the square of its argument for
small arguments, including those for which this results in spurious underflow,
e.g. atanhl (0x1p-10000L) produces a spurious underflow exception.
