NPOI_2.1.3 _ learning records (6)-set decimals, percentages, currencies, dates, scientific counts and amounts in Excel in upper case, npoi_2.1.3-excel Some special values are inevitable during Excel operations. The conversion method is similar below. The Code is as follows: HSSFWorkbook hssfWorkbook = new HSSFWorkbook (); ISheet sheet = hssfWorkbook. createSheet ("Sheet1"); // you can specify the width of the first column (Cell. setColumnWidth (0, 50

Today, the data collected in the database is a bit large, and one output is automatically converted into scientific notation. It was later discovered that there was a problem with the method of converting strings. As follows:String a = "11234567.89";BigDecimal db = new BigDecimal (a);SYSTEM.OUT.PRINTLN ("Scientific count:" + db.tostring ());System.out.println ("Normal count:" + db.toplainstring ());Output:S

Sqlsever scientific notation to standard value, sqlsever count I. Solutions Convert 2e-005 to 0.00002 Update table name set column name = cast (column name as float) as decimal (19,5) where column name like '% e %' If 2e-006 is converted to 0.000002, then decimal (19,6), and so on. Ii. test: Select cast ('+ 1.590759e + 01' as float) as decimal (19,5 )) Result: 15.90759 Iii. Practical application: Hg (mercury, nvarchar type, considering that there are

After PHP json_decode, digital objects are converted into scientific notation.$obj= ' {' order_id ': 213477815351175, ' buyer ': 100001169269154} '; $obj=$this->json_decode ($obj,TRUE); Print_r ($obj);Results:Array ( = 2.1347781535118E+14 = 1.0000116926915E+14)Finally, using PHP's own function Number_format (), the problem is resolved, the effect is as follows:$obj= ' {' order_id ': 213477815351175, ' buyer ': 100001169269154} '; $obj=$this->jso

Problem Description:the 99999.99 is credited to the SQLite database, and the type is decimal (6,3). change to 100000.00 by Cursor.getstring ()and storage of billions of bits of data: cursor.getstring () will be abnormal, or directly converted to scientific notationSolution:1. Read for SQLite data type (even if SQLite is untyped), the decimal type is cursor.getdouble ().2. Do not set the type to SQLite, all with text. about how to change the structure

This afternoon, a friend wrote an algorithm that converts the input integer or floating-point number to the scientific notation expression. After writing the algorithm, he asked me to help him see if there were any bugs or other issues that were not fully considered. I have been scared by the fact that I have not carefully read it-I have written nearly three hundred lines of code. I didn't say anything about him. I just went back to my computer and wr

I am ashamed to say that I have a rough understanding of the entire scientific research process for the first time since I was a second-year graduate student. I would like to thank the book computer vision algorithms and applications. The appendix below contains a lot of useful resources.

As an open-source alternative to Matlab, GNU Ave ave is similar and different. Especially in scientific plotting, it is not a habit to start using it. It cannot be said here. Without commercial support, in the field of professional software, the quality, ease of use and comprehensive functions of open-source software are hard to guarantee: after all, it only provides an open window for advanced users and those who are willing to spend their time on it

Kali linux 2.0 implements scientific Internet access through host machine proxy One of the biggest problems with using kali linux is that it cannot smoothly download and update resources from the official resource library. Now in China, the solution is to first find other unofficial update sources, then download the updates, and then install openvpn (2.0 has been installed by default), and then scientifically access the internet. However, the update s

Installing the scientific computing package numpy and SciPy in Python In Python, the installation of most toolkit is very simple. You only need to execute the "python setup. py install" command. However, the installation process is complicated due to the dependency between SciPy and numpy scientific computing packages. Online tutorials are messy and cannot be used. After carefully studying the README and IN

Anaconda is a scientific computing environment similar to canopy, but it is more convenient to use. The Package Manager Conda is also very powerful. The first is to download the installation. Anaconda provides two versions of Python2.7 and Python3.4, and can be created by Conda if additional versions are required. When the installation is complete, you can see that Anaconda provides Spyder,ipython and a command line. Here's a look at Conda. Enter Con

0.TEX Old MemoriesWhen Professor Knuth wrote TAOCP (the Art of computer programming), he found that booksellers had made the math in his book so ugly that he decided to develop a typesetting language that was well suited to math, so he had Tex, and quickly popular and attracted a lot of science workers to use Tex as a scientific paper writing. (Daniel is Daniel)PS:TAOCP introduction of the website, mainly about the algorithm. Http://www-cs-staff.stanf

The female friend who has had a child should know very well, pregnant special love to eat sour food, of course, also some people love to eat spicy, in fact, this does not mean to eat sour food will give birth to son, because there are many love to eat sour woman also gave birth to daughter. So, what is the reason why you like to eat acid in pregnancy? There is a lot of folk saying is unscientific, and from a scientific point of view to explain, should

Numphp is a NumPy-based PHP scientific computing package. This PHP class library is not designed to solve large computational problems, but rather to support your PHP application to deal with the underlying scientific computing problem.

(0.003) --- true, if the number is small, 0.003 is displayed normally. $ bool16 is too long. If no value is added, the scientific notation var_dump ($ bool) is displayed. // print the result: bool (true) echo""; Var_dump ($ bool2); // print the result: bool (false) echo""; Var_dump ($ bool3); // print the result: int (0) --- false if ($ bool3) {echo" --- true ";} else {echo "--- false" ;}; echo""; Var_dump ($ bool4); // print the result: float (0) --

In this paper, we describe the solution of the conversion of the digital object to scientific counting method after PHP using Json_decode. Share to everyone for your reference, as follows: Problem: Today in the Web game on Facebook points docking, Facebook passed a class JSON string, want to apply these parameters in the callball.php page, so a json_decode operation, found that the long numbers have become scien
