associativity

名词 n.
中文释义

英文释义

名词 n.
  1. The condition of being associative.
    — The associativity of OR and AND is not at all obvious. It is tempting to assume that because OR and AND are commutative that they must be associative also. This is not the case, however, and some commutative Boolean operators are not associative. Examples include NAND and NOR.
  2. The property of an operator which determines how it is grouped with operators of the same precedence in the absence of parentheses.
