The ZZIPlib provides read access on ZIP-archives and unpacked data. It features an additional simplified API following the standard Posix API for file access
When verbously listing a ZIP file with directories, a "Floating point exception" occurs because the uncompressed size "usize" is 0. The fix is to print 100% whenever csize and usize are identical, which they are in case of a directory. This may also prevent spurious rounding problems.
Reproducer:
1) create a zip file from a directory (any)
eg mkdir Test; cp /etc/passwd Test; zip -r Test Test
2) list zipfile using unzip-mem -v: unzip-mem -v Test
Floating point exception (core dumped)
