"If and only if" vs. "if" or "only if", what’s the difference?

In logic and related fields such as mathematics and philosophy, "if and only if" (shortened as "iff") is a biconditional logical connective between statements, where either both statements are true or both are false. The connective is biconditional (a statement of material equivalence), and can be likened to the standard material conditional ("only if", equal to "if ... then") combined with its reverse ("if"); hence … WebThink, your truth table only returns 1 when both conditions are false ( 0 0 -> 1 ).
