bytes in megabyte

English documents:class bytes ([source[, encoding[, errors]]) Return a new "bytes" object, which is an immutable sequence of integers in the range 0 x 256 . was an bytes immutable Versio N of bytearray – it has the same non-mutating methods and the same indexing and slicing behavior.Accordingly, constructor arguments is interpreted as for bytearray() .Descripti

the English character uses utf-8 encoding to occupy a byte, while a Chinese encoding takes 3 bytes, all of which use a byte array of length 25 to hold bytes read from the file). When you get here, do you think that the new newly-created string it internally holds the characters are utf-8 format, the fact is not, has been emphasized, Java is used in Unicode encoding, so at the time of new, The method intern

I found the relevant concepts in the principle of computer composition, and searched the Internet First, in the performance test, any out of the underlying content, for performance testing, is incomplete, any program, what middleware if there is no operating system and computer support, is meaningless, because in the computer world, there are some concepts need we can grasp and understand, such as: bit, word, length First of all, bit: A bit represents a bits, commonly called a bit, is the small

From: http://blog.163.com/wex660@126/blog/static/241530652008111411389746/ Today, my friend has encountered this problem. It seems that I have said it many times, so I will release it to avoid talking about it every time.I. symptomGenerally, this phenomenon is applicable when SQL files are created in the query analyzer. Generally, the following prompts are displayed: "Warning: The table 'xxxx has been created, but its maximum row size (89960) exceeds the maximum number of

This articleArticleThe main purpose is to analyze the storage space used for building the system to avoid the waste of storage device transition and save investment. It also improves the common usage of OracleDataType. IntroductionThe types are as follows:· Char· Varchar· Varchar2· Nvarchar· Nvarchar2· Number· Date The Char length is fixed. For example, if you define char (20), even if you insert ABC, less than 20 bytes, the database will automatic

casecoutsizeof(SS3) //SS3 is also an array of characters, which begins to pre-allocate 100, so it's 100 bits in size.coutsizeof(SS4) //SS4 is also an array of integers, which begins to pre-allocate 100, but the space occupied by each integer variable is 4, so its size iscoutsizeof(Q1) //Q1 and SS2 are similar, so it's 4.coutsizeof(Q2) //Q2 There is a ' \ n ', counted as one, so its space is 3coutsizeof(Q3) //Q3 is a character pointer, the size of the pointer is a fixed value, is 4, so sizeof (Q

Today found a problem, a length set to 2000 bytes of the field, inserting a length of 1000 Chinese characters data, unexpectedly error.A Chinese character accounts for two bytes, which is arguably exactly 2000 bytes. However, by looking at the log, it is found that the length of the inserted data is 3000 bytes.Baidu a bit, the original is a different character se

This article introduces the Python built-in bytes function in detail: Class bytes ([source [, encoding [, errors]) Return a new "bytes" object, which is an immutable sequence of integers in the range 0 Accordingly, constructor arguments are interpreted as for bytearray (). Note: 1. the returned value is a new unmodifiable byte array. each numeric element must b

When a web application displays a string in a browser, due to the display length limitation, it is often necessary to intercept the string before display. However, many popular languages, such as C # and Java, use Unicode 16 (ucs2) encoding internally. In this encoding, all the characters are two characters. Therefore, if the string to be intercepted is a mix of Chinese, English, and numbers, the following string is generated: Code highlighting produced by Actipro CodeHighlighter (freeware)http

Why ask this question, in the first eight basic data types defined in Java, in addition to the other seven types have a clear memory consumption of bytes, the Boolean type does not give a specific number of bytes occupied, because there is no Boolean type for the virtual machine, When a Boolean type is compiled, it is represented by a different data type, how many bytes
