Most programming languages have a native "Boolean" data type. Perl
|
||
|
|
does not.
|
||
|
|
|
||
|
|
Perl has a simple and well known Truth System. The following scalar
|
||
|
|
values are false:
|
||
|
|
|
||
|
|
@false = (undef, 0, 0.0, '', '0');
|
||
|
|
|
||
|
|
Every other scalar value is true.
|
||
|
|
|
||
|
|
This module provides basic Boolean support, by defining two special
|
||
|
|
objects: "true" and "false".
