unix - Script programming and significant figures -

मैं वर्तमान में tcsh का उपयोग करते हुए स्क्रिप्ट बनाने के साथ आसपास जा रहा हूँ और Ive ने देखा है: यदि आप विभाजन करते हैं यह केवल कई महत्वपूर्ण आंकड़े बताता है, जैसा कि तर्क

अर्थात् चल रहा है (संख्याएं दर्ज किए गए तर्क हैं): 

  2/4 आउटपुट 0 4/2 आउटपुट 2 22/2 आउटपुट 11 1/8 आउटपुट 0 9 / 2 आउटपुट 4   
 तो एक ऐसा कैसे बदलता है 1/8 = 0.125, 2/4 = 0.5, 9/2 = 4.5 आदि ??   
 
 
 मनमाने ढंग से परिशुद्धता कैलकुलेटर  बीसी  का उपयोग करें और जो परिशुद्धता आप चाहते हैं वह पैमाने सेट करें:  
  $ bc -e 'पैमाने = 10; 1/8; 4/5; पैमाने = 30; 1/31 '.1250000000 .8000000000 .032258064516129032258064516129

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
