In Perl, you can compare numbers using comparison operators. The following operators are available:
- == Equal to
- != Not equal to
- < Less than
- > Greater than
- <= Less than or equal to
- >= Greater than or equal to
Here are some examples to illustrate how to compare numbers in Perl:
my $num1 = 5;
my $num2 = 10;
if ($num1 == $num2) {
print "The numbers are equal\n";
} else {
print "The numbers are not equal\n";
}
if ($num1 < $num2) {
print "$num1 is less than $num2\n";
} else {
print "$num1 is greater than or equal to $num2\n";
}
if ($num2 >= $num1) {
print "$num2 is greater than or equal to $num1\n";
} else {
print "$num2 is less than $num1\n";
}
In the above example, we have declared two variables $num1 and $num2 and then used various comparison operators to compare these variables with each other.
The first if statement compares if the two variables are equal or not. If they are equal, it will print "The numbers are equal," otherwise it will print "The numbers are not equal."
The second if statement checks if $num1 is less than $num2 and prints an appropriate message based on the result.
Lastly, the third if statement checks if $num2 is greater than or equal to $num1 and prints an appropriate message based on the result.
