That's a good suggestion, but beware that sprintf uses the round-to-even method of rounding. 

$ perl -e 'printf "%.0f\n", 2.5;'

$ perl -e 'printf "%.0f\n", 1.5;'

To get the usual "round up" method, I usually use int with the value plus a half. 

$ perl -le '$x=1.5;print int($x+.5)';
2
$ perl -le '$x=2.5;print int($x+.5)';
