Here is the most basic example of how to divide two numbers in Perl.

#!/usr/bin/perl
use strict;
use warnings;

print (10 / 2);

It is much more common to store the result in a variable.

#!/usr/bin/perl
use strict;
use warnings;

my $result = (10 / 2);
print "result = $result \n";

Which should return the following.

Decimal numbers

By default, decimal will be used.

#!/usr/bin/perl
use strict;
use warnings;

my $result = (10.2 / 2.5);
print "result = $result \n";

Which should return the following.

Whole numbers

The integer module can be used to round to whole numbers.

#!/usr/bin/perl
use strict;
use warnings;
use integer;

my $result = (10.2 / 2.5);
print "result = $result \n";

Which should return the following.
