Operator Name Logical operators Table 4.3–1 Definition ~ NOT ~A returns an array the same dimension as A; the new array has ones where A is zero and zeros where A is nonzero. & AND A & B returns an array the same dimension as A and B; the new array has ones where both A and B have nonzero elements and zeros where either A or B is zero. | OR A | B returns an array the same dimension as A and B; the new array has ones where at least one element in A or B is nonzero and zeros where A B are both zero. and && Short-Circuit Operator for scalar logical expressions. A && B AND returns true if both A and B evaluate to true, and false if they do not. || Short-Circuit Operator for scalar logical expressions. A || B OR returns true if either A or B or both evaluate to true, Z.R.K 4-11 and false if they do not.
Order of precedence for operator types Table 4.3–2 Precedence Operator type First Second Parentheses; evaluated starting <strong>with</strong> the innermost pair. Arithmetic operators and logical NOT (~); evaluated from left to right. Third Relational operators; evaluated from left to right. Fourth Logical AND ( & ). Fifth Logical OR ( | ). 4-12 Z.R.K
