data-conversion

问题 I need to convert data from my csv file to the one i am gonna use which is .js . Lp.;Name;Surname;Desc;Unit;Comment 1;Jan;Makowski;Inf;km; 2;Anna;Nowak;Pts;km;Brak reakcji If you can see column 'comment' does not always have record and I need to keep it that way. Also between data there is amount of tabs I need to set as well. I've a file,i am working on right now but It show's me data in row like : [{"Lp.;Name;Surname;Desc;Unit;Comment": "1;Jan;Makowski;Inf;km;"}, {"Lp.;Name;Surname;Desc

问题 I have an array of char (usually thousands of bytes long) read from a file, all composed of 0 and 1 (not '0' and '1', in which case I could use strtoul ). I want to pack these into single bits, thus converting each 32 char into a single uint32_t. Should I write a bit shift operation with 32 parts, or is there a saner way? out[i/32] = data[i] << 31 | data[i+1] << 30 | data[i+2] << 29 | data[i+3] << 28 | data[i+4] << 27 | data[i+5] << 26 | data[i+6] << 25 | data[i+7] << 24 | data[i+8] << 23 |

问题 When converting an integer to text, typically I create a big buffer to use with sprintf() to hold any potential result. char BigBuffer[50]; sprintf(BugBuffer, "%d", SomeInt); I'd like to more space efficient and certainly portable, so instead of 50 , found the alternative: (sizeof(integer_type)*CHAR_BIT*0.302) + 3 // 0.0302 about log10(2) #define USHORT_DECIMAL_BUFN ((size_t) (sizeof(unsigned short)*CHAR_BIT*0.302) + 3) #define INT_DECIMAL_BUFN ((size_t) (sizeof(int) *CHAR_BIT*0.302) + 3)

问题 I have two polygons with their vertices stored as Double coordinates. I'd like to find the intersecting area of these polygons, so I'm looking at the Clipper library (C++ version). The problem is, Clipper only works with integer math (it uses the Long type). Is there a way I can safely transform both my polygons with the same scale factor, convert their coordinates to Longs, perform the Intersection algorithm with Clipper, and scale the resulting intersection polygon back down with the same

问题 I need some advice on this java method. The intent of this method is to take a string that represents a date - this string was created from a date in the EST time zone - and convert it to a java Date object in the UTC time zone. private Date buildValidationDate(String dateString) throws ParseException { System.out.println("dateString " + dateString); SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyy hh:mm a"); dateFormat.setTimeZone(TimeZone.getTimeZone("UTC")); dateFormat

问题 I am using iText for .NET for converting HTML to PDF. I'm using HtmlParser to convert an HTML page to PDF, but the problem is that Htmlparser only seems to convert the first line to pdf all other lines from the HTML file are not converted to PDF. Here is the code Document document = new Document(); final = new Document(); StreamWriter writer = new StreamWriter("fck.txt"); writer.WriteLine(FCKeditor1.Value); writer.Close(); // Changing the extension of txt file to html file File.Move("C:\

问题 I have a shapefile downloaded from the worldwildlife.org for the terrestrial ecoregions of the world. The file can be loaded here: http://worldwildlife.org/publications/terrestrial-ecoregions-of-the-world. It comes as a standard shape file and I would like to do two things with it. First: take the shapefile from my local directory and clip it to an extent of eastern North America (ext= extent (-95, -50, 24, 63)) # Read shapefile using package "maptools" eco_shp <- readShapeLines("F:/01_2013

问题 Hi I'm trying to create plots which incorporate parallel conversion scales for two sets of units on the y-axis; using the two different styles of: offset ('parasitic') y-axes and overlaid/shared y-axes to replicate the style of the left-hand y-axes in the attached example images. I'd like to find the simplest generic way of producing both of the above example plots, which also allows me to generate the y-axis conversion scales by defining the relationship between the two sets of units as a
