This is a complex symbol composed of two basic mathematical logic symbols. Indicates that the operand is negated first, and then the logical OR operation is performed.

In the logical operation of mathematics, the logical "not" (expressed as! ) takes precedence over logical OR (denoted as ||). So the operation mode of this symbol is to operate first! Recalculate ||.

This symbol is often used in mathematical logic operations, such as a= 1||! B=2, which means that B is negated first, and then the variable A is used for operation. ..

Extended data:

In the logic algebra symbols of mathematics, there is a relation with (&; ), or (|), instead of (! ) three basic logical operations. There are many expressions of logical operations, such as statement description, logical algebra, truth table, Karnaugh map and so on.

Logical operation is a logical deduction method of digital symbolization, including union, intersection and subtraction. This logic operation method is used in graphics processing operation, which makes the simple basic graphics combination produce new shapes, and develops from two-dimensional logic operation to three-dimensional logic operation.
