It seems that perl sprintf uses the round-to-even method:
foreach my $i ( 0.5, 1.5, 2.5, 3.5 ) {
printf "$i -> %.0f\n", $i;
}
__END__
0.5 -> 0
1.5 -> 2
2.5 -> 2
3.5 -> 4
4.5 -> 4
Where we probably wants to use round-half-up, i.e. output should be as below:
0.5 -> 1
1.5 -> 2... (8 Replies)

Is there a way I can round time in perl to the nearest five minutes?
For example if I have log giving the following time stamps
23,52,30 it would rounded up to 23,55,00
and
23,50,01 would be rounded to 23,50,00 (3 Replies)

Hello
I am getting this very annoying issue in awk:
awk '{a=12825;b=a*1.25; print b}' test
16031.2
Thing is the multiplication result is wrong... Result should be 16031.25.
I think the issue only happens on bigger numbers.
What can I do to get passed this?
