It's documented as deprecated, so it probably is. I've never used it, but a few trials turn up some fishy results: 

$ perl -e'$_=1.657329486;$#="%8d";print,print $/'
-330231720
$ perl -e'$_=1.657329486;$#="%05f";print,print $/'
1.657329
$ perl -e'$_=1.657329486;$#="%06f";print,print $/'
1.657329
$ perl -e'$_=1.657329486;$#="%08f";print,print $/'
1.657329
$ perl -e'$_=1.657329486;$#="%s";print,print $/'
Segmentation fault (core dumped)
