Function BAnd() Foundation
Calculates the result of a bitwise AND operation.
BAnd( <nVa1>, <nVal2>, [<nVal3>,...] ) -> nBitwiseAnd
BAnd() returns the result of a bitwise AND operation between operands <nVal1> and <nVal2>. If additional parameters are passed, another bitwise AND operation is performed for each parameter. Once all parameters are processed, BAnd() returns the combined result of the AND operation.
BAnd() is a numeric function that performs a bitwise AND operation between two or more operands. A bitwise AND switches on only those bits in the result which have corresponding bits set in all of the operands. The following table illustrates this correlation.
|Operand 1||Operand 2||Result|
Bitwise operations are usually used with flag values, where a certain bit pattern represents a certain option being enabled or disabled. Using the function BAnd(), a flag value can be easily tested for the presence of a certain option.
