True! And thanks for importing that point into the discussion.
said but true, true but sad. i have already raised the issue on this
list earlier, but to no response. apparently, this sort of excel bug in
r is an intentional feature, so you may not get it improved anytime
soon. unless you submit a patch and get it accepted, that is.
Have you brought this 'issue' up with the Perl people as well?
perl -e 'print sprintf("%.1f", 0.05) . "\n";'
0.1
perl -e 'print sprintf("%.1f", 0.15) . "\n";'
0.1
