may round a float number to the smallest interger bigger than float with using only

printf "%.2f", $x; // or %d

not using ceil() or else . I must add one to result with %d ? what if I can not use if...else... to choose in case not need add one ?

look up the sprintf function for the specific code like this


my $rounded = sprintf("%.2f", $price);


That rounds to two decimal places. I am guessing when I say that %.0f is what you need.

Just read the perl doc and got this which may be of help.


printf '<%.4g>', 100.01; # prints "<100>"
