Operator Types
Explore the different operator types in Perl, such as numeric, string, logical, bitwise, and special operators. Understand how each imposes a specific context on operands and how to use them effectively in various coding scenarios for more precise and maintainable Perl programs.
Perl’s operators provide value contexts to their operands. To choose the appropriate operator, we must know the values of the operands we provide and the value we expect to receive.
Numeric operators
Numeric operators impose numeric contexts on their operands. These operators are the standard arithmetic operators of addition (+), subtraction (-), multiplication (*), division (/), exponentiation (**), and modulo (%), their in-place variants (+=, -=, *=, /=, **=, and %=), and both postfix and prefix autodecrement (--).
The auto-increment operator has special string behavior (discussed under “Special operators” below).
Several comparison operators impose numeric contexts upon their operands. These are numeric equality (==), numeric inequality (!=), greater than (gt), less than (lt), greater than or equal to (gt=), less than or equal to (lt=), and the sort
comparison operator (lt=gt).
