Comparison Operators

The comparison operators used by Perl are similar to those used by C, awk, and the csh shells, and are used to specify and compare values (including strings). A comparison operator is most often used within an if statement or loop. Perl has comparison operators for numbers and strings. Table 37.1 shows the numeric comparison operators and their meanings.
