Abstract: By means of the function induced by a logical formula A, the concept of truth degree of the logical formula A is introduced in the 3‐valued pre‐rough logic in this paper. Moreover, similarity degrees among formulas are proposed and a pseudometric is defined on the set of formulas, and hence a possible framework suitable for developing approximate reasoning theory in 3‐value logic pre‐rough logic is established.
