processes process) process is primarily used to manage access to data blocks within the cluster and to transmit block mirroring in the Buffer cache for different instances. Copy the data block directly from the cache of the controlled instance, and then send a copy to the requested instance. and ensure that the image of one block of data in the Buffer Cache for all instances can only occur once. The LMS process coordinates the access of the data bloc

If it is not clear, many programmers use 0x7fffffff as the infinity, because this is the largest 32-bitint. If this infinity is only used for general comparison (for example, to obtain the minimum min variable), then 0x7fffff

This article describes the attributes and methods of the Number object of the JavaScript native object. This article describes the syntax, MAX_VALUE, MIN_VALUE, NaN, and other attributes or methods for creating the Number object, for more information, see
Syntax for creating a Number object:
The Code is as follows:
Var myNum = new Number (value );Var myNum = Number (value );
When Number () and operator new are used as constructors, it returns a newly created Number object. If the new operator i
To create the syntax for a number object:
Copy Code code as follows:
var myNum = new number (value);
var myNum = number (value);
When number () and operator new are used together as constructors, it returns a newly created number object. If you do not use the new operator to call number () as a function, it converts its arguments to an original numeric value and returns this (NaN) if the conversion fails.
Max_value
The Max_value property is the largest number that can
In the algorithmic race, we often need to use a "infinity" value, for me, most of the time I will be based on a specific question to take a 99999999 of the number (looks very unprofessional ah. )
When looking at other people's Code on the Internet, I often see that they set the INF as 0x7fffffff, wondering why a hexadecimal number is so strange that a check is known because this is the maximum value of 32-bit int. If this

If the argument is a string, it shoshould contain a decimal number, optionally preceded by a sign, and optionally embedded in whitespace. The optional sign may be'+'Or'-';'+'Sign has no effect on the value produced. the argument may also be a string representing a NaN (not-a-number), or a positive or negative
exponent part of the special infinity value is alsoEMax + 1 = 128, but the infinite ending number field must be zero. Infinity is used to express the overflow problem in computing. For example, when two extremely large numbers are multiplied, although the two operands can be saved as floating-point numbers, the result may be as large as it cannot be saved as a floating-point number, but must be rounded. Ac

Some special rules for multiplication operators:
If the operands are numeric, the normal multiplication calculates that if the product exceeds the representation range of the ECMAScript value, return infinity or-infinityIf one operand is Nan, then the return result is NanIf infinity is multiplied by 0, return NanIf the

Logical OR is also a simple operation. For logical OR operators, if the first operation value is true, the second operation is no longer calculated.

1. How to create a blockIn the previous understanding of the basic concepts of blocks in the MongoDB shard architecture, here's how to create blocks? When you decide to assign data, you must select a key for the block interval (we've been using username for the first time) This key is called the Slice key (Shard key), The slice key can be a combination of any field or field, as in the following document:If we select the age field as the slice key and get a block interval [20,26], this block cont
