Bit arithmetic
All the numbers in the program are stored in binary form in the computer's memory. A bitwise operation is a direct manipulation of an integer in-memory bits.bitwise operations-DefinitionIn many system programs, it is often
Bit operation can greatly reduce the complexity of the algorithm space, improve efficiency, very ingenious!Let's talk about the simple use of bit arithmetic.1. Bitwise AND &Purpose: Zeroing, taking some of the points in a number positioning,

Bitwise operations
From groovy 1.0 Beta 10, groovy supports bitwise operations: (supported from grovvy1.0beta10), >>>, |, &, ^, And ~.
Bitwise operators defined by Java performs operations on digits of the integer type directly. These integer types include long, Int, short, Char, and byte. Table 4-2 lists bitwise operations:Table 4.2-bit operators and their results

ECMA-262 describes a set of operators that manipulate data values, including arithmetic operators, bitwise operators, relational operators, and equality operators.The difference between the ECMAScript operators is that they can be applied to many
