metric decimal places

In. when operating databases in. net, we recommend that you use parameterization to pass values. However, this may cause some doubts, for example, how can we maintain the same precision and decimal places as in the database when using decimal? You can use the precision and scale attributes of the parameter, for example: /// /// Update a piece of data/// Publi

Decimal (P[,s]), where p is precision and S is the number of decimal digitsP (Precision) The total number of decimal digits that can be stored, including the number of digits to the left and right of the decimal points (Number of decimal

There are several ways to do this:var test=11111.111;Alert (test.tofixed (2));float data rounded to 2 decimal places;function To2bits (FLT) {if (parsefloat (flt) = = FLT)Return Math.Round (FLT * 100)/100;to 4 decimal places, return Math.Round (FLT * 10000)/10000;Elsereturn 0;}ASP retains two

I have studied how to add, subtract, multiply, and divide JavaScript decimal places. I have also done some tests and gained a lot of knowledge, you can share an interesting test with us as follows: 0.1 + 0.2 = 0.3 // falseSuddenly depressed, okay! 0.1 + 0.2 changed to: 0.30000000000000004Another 2.4/0.8 => 2.9999999999999996 cannot be converted into an integer (2.4*100)/(0.8*100)10.22 now I want to subtrac

things... but IE5.5 + is required. 5. js retains 2 decimal places (mandatory) If the number of decimal places is greater than 2 digits, the above function is no problem, but if it is less than 2 digits, for example: changeTwoDecimal (3.1), 3.1 is returned, if you must use the format 3.10, you need the following funct

I have been engaged in ASP. NET in C # development for almost a year. Today I know that the truncation method is not used when the number of decimal places is retained in C.The project uses the truncation method to get the last two digits of the decimal point, so the following method is written:1 /// 2 // truncate a small value by the specified number of

The project uses the truncation method to get the last two digits of the decimal point, so the following method is written: Copy codeThe Code is as follows: // /// Truncates a small value by a specified decimal point /// /// /// /// Public static decimal ToFixed (decimal d, int s) {

We want to modify the display format of a page's data, which requires two steps:1. In JS through $ ('. Class1. Class2 Li:eq (2) Span.value '). Text (). Trim (); A similar statement gets the contents of the data.2. Modify the data to the desired format. (eg:data=10 ==> 9+1)If we get the data value is an integer, then no problem, things will go well, as expected results.But if you take a decimal, the problem comes.What is this for?A: This is related to

C # decimal retains the specified decimal places, When decimal retains the specified decimal digits, the. NET method is rounding. If the project encounters a apportioned amount, the amount in the last line = total amount-sum of the apportioned amount. This may result in a ne

This article is mainly for JS to retain two decimal places, a number of decimal sample code was introduced, the need for friends can come to the reference, I hope to help youThe code is as follows: There are several methods: The code is as follows: Var test=88888.234; Alert (test.tofixed (2)); float data rounded to 2 decima
