sql - Rounding up and down of numbers with specific decimal points -

-

I am using SQL Server 2008 R2 and round the values ​​with specific decimal points as shown below and below For example:

  1. If my value is 1.27845 and me 2 The answer with decimals is

  2. Rounding down: 1.27

  3. If my value is 33.33333 and I want to reply with 2 decimal places then my answer should be

  4. Rounding UP: 33.34
  5. Rounding Down: 33.33

  6. If my value is 1.27845 and I want to reply with 3 decimal places, then my answer should be

    1. rounding UP: 1.279
    2. Rounding down: 1.278

    3. If my value is 33.33333 and I need a reply with 3 dc

    4. Riding down: 33.333

      I am looking for all matters Valid solution should be thanked ...

      You can use the following "offset" with FLOOR and CEILING 

        DECLARE @ Digit Int = 2, Avilue Decimalian (10,5) = 1.27845 DECLARE @calc_scale int = POWER (10, @ points) Choose Cast (Flow (@value * @calc_scale) / @ calc_scale   
       However, below the target data as DCC (10,5), CAST (CEVLING (@value * @calc_scale) / @ calc_scale AS DCIML (10,5) is always specified in the query (e.g. Edit  : C above A example of scale 5) You can not dynamically change the number of digits in the output, because it depends on the data type of scale variable. You can mess with the conversion of a VARCHAR data type and trim the unwanted numbers, but I am strongly voting against it.  
       If you only need to display the number of significant digits, then I recommend trimming the application layer.

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
