Use JavaScript For hexadecimal conversion and javascript hexadecimal conversion
JS is a magical language. Many internal functions can help us convert data (in;Javascript can be directly in hexadecimal notation;Var a = 0xff; // 255.
Convert any hexadecimal string to decimal, such as binary, octal, and hexadecimal. If the second digit is not written, it is the most commonly used integer decimal;

Convert decimal to binary, octal, and hexadecimal
To convert from decimal to other hexadecimal values, the number is used to continuously divide by the number of hexadecimal values to be converted and read the remainder. Connect them together.
Copy codeThe Code is as follows: /**
* Convert decimal to binary, octal, or hexadecimal with zero padding before the digits being insufficient *
*
* @ Param array $ datalist input data array (100,123,130)
* @ Param int $ bin
The string is "PAYPALISHIRING" written with a zigzag pattern on a given number of rows like this: (You may want to display this pattern In a fixed font for better legibility)P A H NA P L S i i GY I RAnd then read on line:"PAHNAPLSIIGYIR"Write the code that would take a string and make this conversion given a number of rows:String convert (string text, int nRows);convert("PAYPALISHIRING", 3)should return "PAHNAPLSIIGYIR" .Solution: String "01

PHP character encoding conversion class,
support for ANSI, Unicode, Unicode big endian, UTF-8, Utf-8+bom to convert each other.
Four common text file encoding methods
ANSI Code:
No file header (file encoding at the beginning of the symbolic byte)
ANSI encoded alphanumeric account of one byte, Chinese characters accounted for two bytes
Carriage return line break, single byte, hexadecimal representation 0d 0a
Unicode encoding:
File header, hexadecimal

In the previous article go与C基本类型转换 (http://blog.csdn.net/freeape/article/details/51885308), but in the actual project is not only used in the conversion between the basic types, More is the value passing and pointer passing in the function encapsulation, how to carry out various values and pointers in the C function and go?

Mutual conversion between js arrays and strings. Mutual conversion between js Arrays
Many of my friends who are familiar with js have encountered the conversion between js arrays and strings. This article gives a brief introduction. The example is as follows:

The array element needs to be connected to a string using a character. Th
Logop1143 hexadecimal conversion, logop1143 hexadecimal conversionDescription
Compile a program to convert data between two different hexadecimal formats.Input/Output Format
Input Format:
There are three input rows. The first row is a positive integer, which indicates the hexadecimal n (2 ≤ n ≤ 16) of the number to be converted, and the second row is an hexadecimal number, if n> 10, uppercase letters A ~ are used ~ F indicates digital 10 ~ 15. The de
Date string format conversion, string format conversion
Date format conversion is a common problem during development.
For example, the date format is 13.06.2017, June 13, 2017, June 13, 2017, and.
You can use string truncation to format a date in a fixed format.
The extension method converts a date from the original format to the required format:
Public static c
In Java, the forced conversion between basic types is not like this. For example, to convert Integers to strings, you must use Integer. toString () static method or String. the valueOf () static method converts a string to an Integer and must use an Integer. valueOf ().It can be seen that the type conversion in JavaScript cannot be regarded as "forced type conversion
Python implementation of basic hexadecimal conversion method, python hexadecimal conversion
This article describes the basic Conversion Method of python. Share it with you for your reference. The details are as follows:
# Parsing string with base into a number is easynum = int (str, radix) # We have to write our own function for outputting to string with arbitr
Common tags and type conversion, common tag type conversion
Common labels:
Tag semantics: what is the meaning of a tag and what can be done.
Weight, the priority of the object.
Div label, no practical significance.
H tag, with its own default style, such as font-size, font-weight, margin
It is recommended that there be no more than one h1 tag page
It is recommended that there be no more than 12 h2 tag page
