For some reason my sprintf usage is not returning the numbers I had
expected and appears to be rounding down. Is there something wrong
with my formatting below.
my $ksize = sprintf("%.2f",$size/1024);
my $mbsize = sprintf("%.2f",$ksize/1024);
my $msize = sprintf("%d",$mbsize);
The %d format is for integers, so it always truncates any fractional
part. The %f is floating, so it rounds. If you want to round to the
nearest integer, then, use a format like "%.0f" or "%6.0f".
Does that solve your problem? The sprintf documentation in the
perlfunc manpage is quite extensive.
