why use integers

See: http://blog.yemou.net/article/query/info/tytfjhfascvhzxcyt346This is a very interesting discussion topic.If you run the following code 1234

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

For example, if the amount is 100.02, then the database needs to be saved as 10002. Reply content: For example, if the amount is 100.02, then the database needs to be saved as 10002. Hope to help you: Code Puzzle (iv)-floating point

For example, if the amount is 100.02, the database requires 10002 storage. For example, if the amount is 100.02, the database requires 10002 storage. Reply content: For example, if the amount is 100.02, the database must be saved as 10002 Hope

For large integer calculations, it is common to use some method of conversion, otherwise it will overflow. But Python has no such concerns. Python supports "infinite precision" integers, generally without the problem of integer overflow, and the

Some scripting languages, such as awk and Lua, use floating point numbers to store integers. That is to say, the integers we use in the language are represented by floating point numbers in the language. We know that there are usually some errors in

IntroductionIn one of my previous articles [ThoughtWorks Code Challenge--fizzbuzzwhizz Game General High Speed (C & C + +)] It was mentioned that the compiler was optimized to handle the division of the divisor as a constant, sorted out today, One

Title: Enter an integer n to find the number of occurrences of 1 in the decimal representation of 1 to n integers. For example, the input 12, from 1 to 12 of these integers containing 1 of the number has 1,10,11, and 12, 11 appeared in total 5 times.

Title: Enter an integer n to find the number of occurrences of 1 in decimal notation from 1 to n integers. For example, enter 12, from 1 to 12 these integers contain 1 of the numbers have 1,10,11, and 12, 11 have appeared 5 times.Method One: Do not

IdeasUse a loop to move an integer to the left I bit, and take the highest bit, if the current maximum is 1 then the value is ' 1 ', otherwise ' 0 '. This stitching out a string.Note: The digital complement is stored in the computer.About positive,
