So I'm wondering if anyone knows of a way I could implement either a floating-point to binary (digits) function or, better yet, floating-point to hex. The best I've been able to come up with so far is a decimal to binary/hex function... 回答1: lua-MessagePack . A big thank you goes to him. function float2hex (n) if n == 0.0 then return 0.0 end local sign

I am splitting values in my data frame by group, bins and by sign, and I am trying to get a mean value for each group/bin/sign combination. I would like to output a data frame with these counts per each group/bin/sign combination, and the total numbers per each group. I think I have it but sometimes I get different values in base R compared to the output of ddplyr. Am I doing this correctly? It is also very contorted...is there a more direct way? library(ggplot2) df <- data.frame( id = sample(LETTERS[1:3],

The problem is that the search pattern contains an equals sign which is messing up the string replacement in the batch file. I want to replace the line, <j2se version="1.5" initial-heap-size="100M" max-heap-size="100M"/> with specific settings for the initial and max heap sizes. For example at the moment I have, for /f "tokens=* delims=" %%a in (%filePath%agility.jnlp) do ( set str=%%a set str=!str:initial-heap-size="100M"=initial-heap-size="

I have been digging around all day trying to figure it out, and I am so close yet so far away . All that is missing is this: How do I get an IExternalSignature object to sign the PDF file with? Rahul Singla has written a beautiful example of how to sign a PDF document using the new iText 5.3.0 API - as long as you can access a .pfx file sitting around on your PC somewhere. There is a previous question on signing using a certificate from the

'+' : '-' end Is there a built-in Ruby method which does that? 回答1: Here is a simple way to do it: x = -3 "++-"[x <=> 0] # => "-" x = 0 "++-"[x <=> 0] # => "+" x = 3 "++-"[x <=> 0] # => "+" or x = -3 "±+-"[x <=> 0] # => "-" x = 0 "±+-"[x <=> 0] # => "±" x = 3 "±+-"[x <=> 0] # => "+" 回答2: I think that it's nonsense not to have a method that just gives -1 or +1. Even BASIC has such a function SGN(n). Why should we

If the bit in the bitmap is black, store a 1. If white, store a 0. E.g.: for bitmap: bbbw bbbw bbbw wwww my short is: 0000 0111 0111 0111 The 1st way I tried to do this was: short m; // ... Color c = bmp.GetPixel(j, i); if (c.R == Color.Black) m |= short.MinValue; m >>= 1; // ... After one assignment and shift, I got the expected -32768 (1000 0000 0000 0000). After the 2nd time I got -16384 (1100 0000 0000 0000). I changed my code to use

On my first attempt I created a new CSR and got the message above. The second time I reused my original CSR and got the same result. Another strange thing is the new certificate has an extra string with brackets after my name in the "common name" when I look at it using Keychain Access like this:
