Name

pgbooln — return undef (NULL), "f" (false) or "t" (true), depending on input data

DESCRIPTION

The filter returns undefined value (NULL) if the input is undefined. It returns "f" (false) if the input is 0, f or false (in a case-insensitive manner). Otherwise, it returns "t" (true).

EXAMPLES

No examples are available at this time. We do consider this a problem and will try to supply some.

NOTES

For more information on Perl Regular Expressions, pattern matching and character classes, see perlre(1).
