Perl does not have a strict distinction between string and numeric
data. They are both considered scalars. The difference comes in how
you use the scalar value.
Try this:
$a = "10";
$b = "2";
if ($a < $b) {
print "numeric: $a is less than $b\n";
}
else {
print "numeric: $b is less than $a\n";
}
if ($a lt $b) {
print "string: $a is less than $b\n";
}
else {
print "string: $b is less than $a\n";
}
Output is:
numeric: 2 is less than 10
string: 10 is less than 2
