how to get two decimal places in java

1. The dumbest way ... [I'll do what I do ...]function Get (){var s = 22.127456 + "";var str = s.substring (0,s.indexof (".") + 3);alert (str);}2. Regular expression effect is good3. He is more clever ...4. Friends who will use new things .... But we need ie5.5+ to support it.from:http://xinlingwuyu.javaeye.com/blog/175931JS retains 2 decimal places after the

Share an interesting test with everyone: 0.1+0.2 = = 0.3//falseSuddenly depressed, OK! The original 0.1+0.2 into: 0.30000000000000004One more 2.4/0.8 =>2.9999999999999996 no way to change it, all of them are converted to integers (2.4 * 100)/(0.8 * 100)10.22 now to subtract 0.11 results and a lot of decimal 10.110000000000001, and then I used the ToFixed method to filter decimals, but I do not know the same as before the conversion to an integer afte

; modify data type interface, there is an option to modify the amount of the data type. I flipped through the code, the setting in this place only affects the EDT type amoutmst, so the EDT type inherited from amountmst is affected, but the amount represented in the original currency like the sales amount is inherited from amount, therefore, the modification here does not affect the number of digits displayed in the sales order line. Here, we modify the value of EDT saleslineamount to four digits

(1) php keeps three decimal places and rounding them The code is as follows: $ Num = 0.0215489;Echo sprintf ("%. 3f", $ num); // 0.022 (2) php keeps three decimal places not rounded.

ArticleDirectory Requirement Overview Implementation Requirement Overview In some statistical reports, the value range of a certain number is quite large. In order to reduce the total number of digits displayed for a large data, a small data must be displayed with sufficient precision, that is to say, different decimal places are displayed based on the data size, which is similar to the

Usually using WPS Mobile version of the table, found that in the statistical data process, in many cases to be rounded to the decimal point two decimal digits.

In javascript, regardless of Single-precision float and double-precision, all decimal variables are regarded as float. Therefore, to obtain the n digits after decimal places, use the toFixed (n) method to obtain Convert js numbers to float and take N decimal places: ====
