Hello,
I want to convert the int for string, then use the
function lenght, and return the size of string.
How It is possible ?
Perl automatically converts a number to and string (and back again) as needed.
To get the length of its string, use the length function:
my $length = length( $number );
Example of automatic conversions:
#!/usr/bin/perl
use strict;
use warnings;
# set $num to a number
my $num = 123;
# convert it to a string for printing
print "$num\n";
# concatenate the character zero to its end
$num .= '0';
# print the string
print "$num\n";
# divide the string by 2
$num /= 2;
# convert it to a string for printing
print "$num\n";
# convert to a string and get its length
print length($num), "\n";
__END__
