Summary: expl (709.75) wrongly overflows for ldbl-128ibm
Product: glibc
Version: 2.15
Status: NEW
Severity: normal
Priority: P2
Component: math
AssignedTo: unassigned@sourceware.org
ReportedBy: jsm28@gcc.gnu.org
CC: sjmunroe@us.ibm.com
Classification: Unclassified

For powerpc-linux-gnu, expl (709.75) wrongly returns infinity instead of the
correct finite value. exp (709.75) correctly returns a finite value slightly
below DBL_MAX.

I believe this value should be adjusted to higher one, 709.78271289338399678773454114190492789L. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
