New commits: commit 28521056a22719dffa0814883d06a7c9531b02ad Author: Eike Rathke <[email protected]> AuthorDate: Wed Nov 25 13:54:31 2020 +0100 Commit: Michael Stahl <[email protected]> CommitDate: Thu Nov 26 10:02:08 2020 +0100 Related: tdf#136272 accept 1.79769313486232e+308 as DBL_MAX This does not solve writing the badly rounded value, which still has to be fixed, but at least be able to read/convert it back as double max value. This is not even used in the bug scenario because the "fake" condition in that number format is discarded anyway because it was only written to satisfy ODF, but it helps in case a 1.7976931348623157e+308 value was entered/used on purpose.
