Question: At Perl, what is the equivalent function of Ceil? Or how can I perform Ceil on a number like other languages.
Answer: So far, I don't know any function to serve this issue. But if I need, I use sprintf() combined with floating. Below example will show you what exactly I mean for.
my $number = 10.51;
$number = sprintf("%.0f", $number);
The above code will output 11, which is the exact ceiling of 10.51.
