The following are the comparison operators.
| Operator |
Function |
| == |
eq |

| != |
ne |
Not Equal to Operator |
| < |
lt |
Less than Operator |
| > |
gt |
Greater than Operator |
| <= |
le |
Lessthan or Equal to Operator |
| >= |
ge |
Greater than or Equal to Operator |
Example:
4=4 or 4 eq 4 # returns TRUE
5!=4 or 5 ne 4 # returns TRUE
5<4 or 5 lt 4 # returns FALSE
5>4 or 5 gt 4 # returns TRUE
5<=4 or 5 le 4 # returns FALSE
5>=4 or 5 ge 4 # returns TRUE
In the above statements "<=, >=" returns true even if both the values are same.
Example:
#! C:\programfiles\perl\bin\perl
print "content-type: text/html\n\n";
$a=1;
$b=5;
if ($a==$b)
{
print "Both the numbers are Equal";
}
else
{
print "The numbers are not equal";
}
Result:
The numbers are not equal
In the above code we just compared two values to display the appropriate results.
