[jira] [Updated] (PDFBOX-3116) COSNumber NumberFormatException for
large number
[ https://issues.apache.org/jira/browse/PDFBOX-3116?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Maciej Woźniak updated PDFBOX-3116:
-----------------------------------
Attachment: PDFBOX_3116.patch
I've added COSDouble class. Minimum and maximum values for float type are much smaller than for double. When we use COSFloat, we get exception:

Also the problem is (partially) resolved, I think.
