1. Problem with type conversion Question: Byte B = (byte) 0x90; how much is equal to? -112 Analysis: (1) int occupies 32 digits and byte is 8 bits (2) Whereas 0x90 may appear to be expressed in 8 digits, but Byte is a -128~127 because it is a

Bitwise -AND Operator (&)Participate in the operation of the two data, press bits for "and" operation.Arithmetic Rules:0&0=0;   0&1=0;    1&0=0; 1&1=1; that is, the two-bit is "1" at the same time, the result is "1", otherwise 0For example: 3&5 is 0

Bit arithmeticA bitwise operation is a binary representation of a number, a 0 or a 1 operation on each.The first step in understanding bit arithmetic is to understand the binary. Binary means that each digit of the number is 0 or 1. For example,

Document directory Bitwise OR operator (|) XOR operator (^) Inverse Operator (~) Left shift operator ( Shift right operator (>) Compound assignment operator The two data involved in the operation perform the "and" Operation in binary bits.

JavaScript Quick Start (5) -- Expression operationsValue assignment is in the form of Left = right. If multiple value assignment operations exist in the same expression, the value is calculated from right to left. For example: A = B = c; // and the
