math - Javascript Rounding to the nearest 2 decimal (however 5 rounds down) -

-

All my values ​​are coming back from the server as 3 decimal places. I have to score 10, 2 decimal places in the nearest place, in the past. Grip from decimal (18,2) decimal (18,3) is that when it is a 5, then it needs to be rounded.

I need to do this in javascript: D

I can not guarantee that 3 decimal places will return, this is the maximum. ex 4.494 - & gt; 4.4 9 ** East 4.4 9 5 - & gt; 4.4 9 ** East 4.496 - & gt; 4.50

It seems that you only want special rounding, where the final digit is 5, so the exam is for him and in those cases differently Do the goals from: PreRound function ends in myRound (n) {// if .nn5, then round if (/ \. \ D \ d5 $ /. Test ('' + N)) {n = Math.floor (n * 100) / 100; } // apply normal spherical return n.toFixed (2); } Console.log (myRound (4.494)); // 4.49 console.log (myRound (4.495)); // 4.49 console.log (myRound (4.496)); // 4.50

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...
