Sharing of the four digital kilobytes of characters formatting methods implemented by JS, js kilobytes
The so-called number is represented by a comma (,) between each three digits starting from the single digit. For example, "10,000 ". In response to this requirement, I initially wrote a function like this:Copy codeThe Code is as follows:// Method 1Function toThousands (num ){Var result = [], counter = 0;Nu
Use of converting JSP Integers to kilobytes (Code instances)Use of converting JSP Integers to kilobytes (code example)
// Use the function formatNumberToStr (mVal, iAccuracy) {var fTmp = 0.00; // temporary variable var iFra = 0; // var iInt = 0 in the fractional part; // integer part var aBuf = new Array (); // output cache var bPositive = true; // Save the positive and negative values mark (true: Positive)
Javascript converts numeric values to the amount format (separated by kilobytes and automatically added decimal points), and javascript decimal points
In the project, if a number similar to '123' needs to be converted into the accounting format, '123' is automatically filled when the number of sub-places is separated by two digits after the decimal point is not enough, several implementation methods have been recorded
Ps: if you do not consider the de
Please implement a js script, which requires that the number be converted into kilobytes, for example, 10000 is converted to 10,000Implement a js script to convert the number into a kilobytesFor example:10000 ----> 10,000
10000121213 ----> 10,000,121,213
I accidentally saw this question today and thought about four solutions to share with you:
// Method 1 function parseNum (num) {var list = new String (num ). split (''). reverse (); for (var I = 0; I
In today's project, we need to display the number of clicks in the article on the page, which is tens of thousands of requests. Although it is not difficult, it has been a programmer for so long, it is no longer a simple implementation, and it is efficient and fast. Although the built-in function number_format () in PHP can achieve sub-bits, what I want is a ten-thousandth bit.

Js formatting amount. Optional values: whether to include kilobytes of data, optional reserved precision, and found on the Internet.Copy codeThe Code is as follows:/*Round the value and format it.@ Param num value (Number or String)@ Param cent: Number of decimal places to be retained)@ Param isThousand whether the Sub-location is required: 0: not required, 1: required (value type );@ Return: a string in the format of '20140901'@ Type String*/Function

First look at my own experimental environment is in what kind of archiving mode:
Sql> Select T.log_mode from V$database t; Log_mode------------Noarchivelog
Two. After determining that it is in the non-archive mode, I first create a regular table t_test_nologging
1. Create a table, the so-called general is in the creation process does not specify this table is nologging
Sql> CREATE TABLE t_test_nologging as SELECT * from T_down_log where 1=0; Table created sql> Select COUNT (*) from T_down_log;
