Re^2: printing true false values by HarshaHegde (Sexton) on Dec 30, 2007 at 16:15 UTC
Thanks Jason and FunkyMonk, for the quick response. I did think of doing something similar: using the if else. However, by the definition of truth values in perl, 0 represents false and anything else represents true. So, if a boolean expression evaluates to true, it will return a 1 and if it evaluates to false, shouldn't it return a 0?	[reply]

perlsyn.pod says: Truth and Falsehood The number 0, the strings ’0’ and ’’, the empty list "()", and "undef" are all false in a boolean context. All other values are true. Negation of a true value by "!" or "not" returns a special false value. When evaluated as a string it is treated as ’’, but as a number, it is treated as 0.	[reply]
Re^3: printing true false values by Somni (Friar) on Dec 30, 2007 at 16:26 UTC
What values are considered true and false is not the same thing as what an expression evaluates to. Many Perl operators that evaluate to a boolean evaluate to 1 when true and `''` (the empty string) when false.	[reply] [d/l]
