A.9 Operators
Operators are
functions
that represent basic operations on values: addition, subtraction,
etc. They are frequently used and are core parts of the Perl
programming language. They are really just functions that take
arguments. For instance, + is the operator that
adds two numbers, like so:3 + 4;
Operators typically have one, two, or three operands; in the example
just given, there are two operands 3 and
4.Operators can appear before, between, or after their operands. For
example, the plus operator + appears between its
operands. |
