Author: robak (ports committer) Date: Tue Jul 3 14:40:19 2018 New Revision: 335890 URL: https://svnweb.freebsd.org/changeset/base/335890 Log: MFC r327317: humanize_number(3): fix math edge case in rounding large numbers Fix for remainder overflow, when in rare cases adding remainder to divider exceeded 1 and turned the total to 1000 in final formatting, taking up the space for the unit character. The fix continues the division of the original number if the above case happens -- added the appropriate check to the for loop performing the division. This lowers the value shown, to make it fit into the buffer space provided (1.0M for 4+1 character buffer, as used by ls). Add test case for the reported bug and extend test program to support providing buffer length (ls -lh uses 5, tests hard-coded 4).
