Bug Fix Advisory libdfp bugfix update

Advisory: RHBA-2011:0659-1
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2011-05-19
Last updated on: 2011-05-19
Affected Products: Red Hat Enterprise Linux Server Supplementary (v. 6)


Updated libdfp packages that fix various bugs are now available for Red Hat
Enterprise Linux 6.

The libdfp packages contain the Decimal Floating Point C Library, which is inter
alia used for converting strings into decimal floating point numbers.

The libdfp packages have been upgraded to upstream version 1.0.6, which provides
a number of bug fixes over the previous version. (BZ#642693)

Additionally, this update fixes the following bugs:

* Previously, converting a string into a decimal floating point number greater
than zero and less than one caused an error. During this conversion, the first
decimal digit disappeared; consequently all following computations were done
with wrong numbers. This bug has been fixed so that the conversion into the
decimal floating point number now works as expected. (BZ#625495)

* Under some circumstances, libdfp encountered an issue while converting a value
from a string into a decimal floating point number with the conversion command
"strtod32". The "strtod64" and "strtod128" commands, which are also included in
libdfp, did work correctly. The problem has been resolved so that the conversion
now proceeds properly. (BZ#628670)

* Previously, there were several testsuite failures encountered when building
the libdfp packages for the IBM S/390 architecture. These testsuite failures
have been corrected with this update and thus no longer occur. (BZ#673222)

All users requiring libdfp should upgrade to these updated packages, which fix
these bugs.


Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
