JavaScript-based formula interpreter-10 [Implementation of bitwise operators]

Base type of bitwise operators

Bitwise operators have the same element and binary type.

File: OperatorBitwiseBase. js

Function OperatorBinaryBitwiseBase () {<br/> this. deriveFrom (new OperatorBinaryBase (); <br/> this. set_ClassName ("OperatorBitwiseBase"); <br/>}; </p> <p> function OperatorUnaryBitwiseBase () {<br/> this. deriveFrom (new OperatorUnaryBase (); <br/> this. set_ClassName ("OperatorUnaryBitwiseBase"); <br/>}; <br/>
