different (wrong) results on comp-3 depending on fnotrunc Hi guys,
I'am using OC 1.1 on suselinux. Have a look on this simple program named cobnum.cbl: Compile this programm with cobc cobnum.cbl. Run this program with cobcrun cobnum and you will see (all is okay): Now compile this programm with cobc -fnotrunc cobnum.cbl. Run this program with cobcrun cobnum and you will see (the first result is quite wrong) : Why does the fnotrunc-option weight the computation of com-3 fields?? This seems to be a serious bug. With kind regards Michael  |

I'm not going to pretend to be that guy, but Sergey has a good eye to find numeric inaccuracies and the skill to fix them. Watch the SourceForge SVN tree. Sergey has already posted some updates, libcob/numeric.c was one of the files patched so far. Not for this issue though. But do keep an eye of the forge at http://sourceforge.net/projects/open-cobol/ and http://open-cobol.svn.sourceforge.net/viewvc/open-cobol/ Cheers, Brian |

Re: different (wrong) results on comp-3 depending on fnotrunc Hi Brian,
can you please add these two samples to the test suite (it's better to have a failed test in trunk than a bug we forget to fix - or to add a similar bug later on). If it's possible I'd like you to add a test for every bugfix that is checked in. Pleeeeaaase. Simon 'human' Sobisch |

Re: different (wrong) results on comp-3 depending on fnotrunc Hi Sergey,
we checked out the newest version today (09/10/2012), but the bug is still present. The module numeric.c was recently changed in september. Michael |

Re: different (wrong) results on comp-3 depending on fnotrunc Updated to the latest from SVN today - I don't see this error. Everything is correct.
And, BTW, I added one thing to your test. If you still have this bug, you will see funny result.
