# Numeric Comparison
$value1 = 10;
$value2 = "10";
if ($value1 == $value2) {
    print "Numeric comparison: Equal\n";  # This will be true
}

# String Comparison
$value1 = "10";
$value2 = "10";
if ($value1 eq $value2) {
    print "String comparison: Equal\n";  # This will also be true
}

# Using alternative approach with Scalar::Util
use Scalar::Util qw(looks_like_number);
if (looks_like_number($value1) && looks_like_number($value2)) {
    print "Both are numbers\n";
} else {
    print "At least one is not a number\n";
}
