Convert integers into binary values and display them. Convert integers into binary values.
During development, you often encounter multiple logo selections. For example, if you save the listbox selection result to the database, the best way is to use a binary flag for each option and set each flag to 1, you only need to accumulate the results of each selected option to save it to the database.

Summary of multiple methods for determining integers in JavaScript, javascript Integers
I have previously recorded multiple methods for determining the digit type in JavaScript. This article describes how to determine the Integer type ).
JavaScript does not distinguish between integers and floating-point numbers. All numbers are expressed in 64-bit floating-point
Storage and operation of integers in calculation, and storage of Integers
The first digit of an integer indicates the symbol bit.
1 positive integer
A positive integer is stored in binary format in a computer. For example:
short s = 3;3 = 2 ^ 1 + 2 ^ 0
A short integer is generally two bytes, that is, 16 bits. Its storage method is as follows:
0 000 0011
Therefore, the short integer is represented in the r

Topic:
Given two integers a and B, it is required not to use ' + ' and '-' to return the and of the two integers.
Ideas for solving problems:
Because the subtraction symbol cannot be used, it is considered that the bitwise-and-bitwise-OR-bitwise operation of the binary number is known to be a^b or can be obtained without taking into account the result of the rounding, bitwise and ab of the case where the
1. Representation of unsigned integers we know that unsigned integers are stored in binary form inside the computer, for example, we declare and initialize a variable in the C language:int i = 66; Suppose that the machine we are targeting is a 32-bit machine, and the byte order is little endian. Since the int type is 32 bits, the number 66 is stored as its 32-bit binary representation (01000010 00000000 00
