How do I have it auto return the best reply, example:
sub get_var_size {
return sprintf("%.02 KB", length($_[0])/1024); # 0.76 KB
}
Sometimes the var length can be 6000 characters or 20000 ...
thanks
sub get_var_size {
return sprintf("%.02 KB", length($_[0])/1024); # 0.76 KB
}

sub get_KB_size {
return sprintf("%.2f", length($_[0])/1024); # 0.76 KB
}
argh - I need more coffee in the morning. Previously forgot about the 'f' suffix. the zero sign is here optional.

$varKB = printf("%.01 KB", $var/1024); # 0.7 KB
$varKB = printf("%.02 KB", $var/1024); # 0.76 KB
$varMB = printf("%.02 MB", $var/1048576); # 0.00 MB
$varMB = printf("%.03 MB", $var/1048576); # 0.001 MB
and so on...
