Have done many times to export Excel. Have encountered a problem, if the content contains a relatively long number, such as the order number "2546541656596", Excel will automatically become the scientific counting method ...Did not solve several times, and recently also exported Excel, determined to find a solutionIn Excel, the longer numbers are automatically turned into scientific notation unless we set the cell format to "text"Haha, seems to find t

Minimum notation: When given a string, the smallest representation of the case, such as: Baab minimum representation is: AABB is the second position of a into the first position.Maximum representation: For example ABCD maximum should be: DABC the basic concept and the minimum notation are the same.Time complexity: O (n)Application: Compare whether the two ring strings are the same string, judge the weight,

This article mainly introduces how PHP converts scientific notation to the original numeric string. It is a very practical technique to implement this function through a simple custom function using regular expression replacement, for more information, see This article mainly introduces how PHP converts scientific notation to the original numeric string.

-Concept:Large O notation: called a function g (n) is O (f (n)), when and only if there are constants c>0 and n0>=1, all n>n0 have |g (n) |-Express meaning-he represents the number of times an algorithm needs to be counted in the worst case scenario. For example, in a phone book (n phone) to find a phone, using quick Find, the best case is to find the first time, the worst case is the nth time to find. This run time is calculated as the worst case O (

The main differences between DB2 and ORACLE SQL notation To be honest, Oracle has spoiled the country's programmers, and SQL in the code is flooded with Oracle features, and almost no one knows what ANSI's standard SQL looks like, leaving the program out of Oracle at all, and the situation has changed dramatically with hibernate.DB2 as the choice of many international major customers (said the world's top 500 80% with DB2, the top 100 are

will encounter invaliduserinsession problem, this only you will encounter when using IE, just remember a little, do not put a comma in front of the curly braces, you will not have trouble.Another very handy shorthand is for arrays. The traditional way to define arrays is this:1 var moviesthatneedbetterwriters = new Array (2 ' Transformers ', ' Transformers2 ', ' Avatar ', ' Indianajones 4 ' 3);The abbreviated version is this:1 var moviesthatneedbetterwriters = [2 ' Transformers ', ' Transformer

A problem found during my internship was that the large floating point number was removed from the database and then changed to the scientific notation display. However, the original verification control did not recognize the scientific and technical methods, which made the data unable to be properly stored, A solution is found temporarily. When big data is input, the floating point type is displayed in scientific
