When parentheses are used, as in this example, they determine the order of operations explicitly. Alternatively, the order of precedence of the logical operators may be used: NOT has the highest precedence, followed by AND, and then by OR, which has the lowest precedence. Any use of ...
Kevin Dotremont, in Handbook of Surgical Planning and 3D Printing, 2023 3.4.1.5 Boolean operations A Boolean operation is an operation that works based on an intersection between two structures. The Boolean union unites everything while keeping the intersecting region only once, and the Boolean sub...

• Order of operations is && before || so this simplifies to false || false = false. • !(true && false) || true • We don’t need to think about the first half because as soon as we see || true, we know this one is true. We’ve found our answer, but let’s keep ...
For operands of the integral numeric types, the &, |, and ^ operators perform bitwise logical operations. For more information, see Bitwise and shift operators.Logical negation operator !The unary prefix ! operator computes logical negation of its operand. That is, it produces true, if the ...

This way, data of the specified type appears only once in the query results. For more information, see Collapse (distinct). If you want to analyze data in a data table, such as obtaining the extreme values, sum, and total number of rows, you can perform aggregation operations or ...
The dual of a function is obtained by changing the AND operations to OR operations and vice versa, and simultaneously changing any 1's to 0's and vice versa. Thus the dual of the function f = (ABC¯ + CD + B¯) is given by fd(A, B, C, D)=(A+B+C¯)(C+D)B...
