Subject: [Bug math/14036] New: exp(710.0) fails to set the overflow exception flag
Date: Sun, 29 Apr 2012 21:43:00 -0000 [thread overview]
Message-ID: <bug-14036-131@http.sourceware.org/bugzilla/> (raw)
http://sourceware.org/bugzilla/show_bug.cgi?id=14036
Bug #: 14036
Summary: exp(710.0) fails to set the overflow exception flag
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: math
AssignedTo: unassigned@sourceware.org
ReportedBy: kreckel@ginac.de
Classification: Unclassified
Created attachment 6382
--> http://sourceware.org/bugzilla/attachment.cgi?id=6382
test case
Using the current HEAD of glibc on an x86-64 system,
When I run the attached program using current HEAD after compiling glibc on an
x86-64 system, I get:
exp(710) returned inf
IEEE754 exception flags: none
exp(-1234) returned 0
IEEE754 exception flags: none
The first one should have set the OVERFLOW exception flag, the second one the
UNDERFLOW exception flag.
(This appears to have broken recently.)
