To obtain a specified integer or decimal number by Math.Round.

The consumer module in the message middleware is responsible for receiving the message from the producer, in the design time, will carry on a cluster management to the consumer, the same cluster identifies the consumer, will constitute a big consumer cluster, as a whole, receives the producer to deliver the message. In addition, the consumer receives a message related API to the client to make the call.

The producer module in message middleware, which is responsible for the production of a specific subject (TOPIC) message, is passed on to the consumer interested in this topic, and also provides the API interface for the producer to produce the message for the client to use.

There are two possible realities: one has a inflection point that allows you to accumulate the corresponding price, and the other may not have this inflection point, stay in a certain level. And the inflection point is probably the opportunity that we often say in reality.

In any case, to get the chance of inflection, you can only continue to accumulate.

First, here is an example of the process of I and J traversal: Zhuazhuangding. Imagine that the [left, right] part of this array is actually a presence, two groups I and J come to zhuazhuangding, they have their own way of judging a person who is supposed to be a group, if I find out that I actually found a J person, I'm sorry, you wait, I swapped you and J to find the I person. Then this I and J find their own team to grow up, to the end, followed by a group of I, J followed by a group of people J. What will happen in the end? It was the meeting of I and J. The important meaning of the partition that this process reveals is the partitioning of arrays.

is a class designed specifically to compensate for the lack of accurate calculation of floating-point numbers, and it also provides a common mathematical algorithm for subtraction. BigDecimal is the optimal solution, especially when it is mapped to a field with a database decimal type.

By enlarging the value of the participating operation by 100 times times and converting it to an integer and then reducing it by 100 times times in the presentation, the benefits of this processing are simple and accurate, and generally more widely used in non-financial industries such as the retail industry. This method is also used in some retail POS machines, where all of the inputs and outputs are integers, and the operation is simpler.

After one months of contact with SOLR, I want to take advantage of the learning SOLR by the way to pick up Java. I use 4 respectively. Versions x and 5.X have built their own in a Windows environment in a jetty way, tomcat deployment. There are changes from 4.x to 5.x and 6.x. Set up SOLR after I use the method of invoking HTTP interface, solrnet implementation of the index to delete and change, in the use of solrnet development, found that the query also reported error, do not know is not because SOLR version is too high. In the process of learning SOLR, refer to a few master's blog, from the platform, create indexes, search index data, Chinese word breakers have learned some, the latter will be sorted out. I will post the link at the end of the article.

There are three ways to solve this problem: 1. Display by converting to UTF-8 encoding. 2. Use the Iconv library to resolve. 3. Use parse XML or JSON file to resolve. It is recommended to use the third method to solve this problem, because it is simpler and more convenient, and can support i18n internationalization.

Do not think that the interface long ugly, after all, the function is still able to use, compared to the web version, but also used in the intranet ... There have been people yelling that the web version can't be used in the net, and now it's enough for you.

The Catch method also returns a promise, so the chain method can then be used after the catch, but then the error will not be captured by the previous catch, which pauses the next blog post-you draw my guess, because in this game, Want to use the latest NG2 technology, but the pit is a piece after another, this way first introduced the environment deployment and pits history

Since to use NG2, first to get resources, I use the AngularJs2 beta version of the online resources have two kinds, One is a full-compressed version of the file. Min.js version of the other is a lot of messy JS files, mainly ng2 has been fully adopted typescript, coupled with support for ES6, so need to introduce a lot of compatibility, and then submitted to the system, the system needs to verify that the origin and other origin overlap, overlap more than 10 % will be warned that the origin has been XXX registered in storage. The data measured by GPS measuring instrument is continuous longitude and latitude coordinate data. Now the question is translated into whether there is an intersection between a series of points and other regions. To get this demand, I think it should be very simple, there should be a ready-made code on the Internet.
