symbols

问题 I want to change the currency symbols in iPhone app based on user's localization. If my app is working in US i need to change the currency symbol "$". If the app is working in Eroupe countries, we need to change the symbol to "€", if the app is in Japan, the symbol should be change to "¥" and if the app is running in Australia the symbol should be in "$". By this way if the app is running in any country the app should be change the currency sign based on the localizations. I have used this

问题 Does anyone know how to place a formula, a (weird) character, or words in italic within a sentence of a footnote of a table? I'm creating a pdf file with Rmarkdown and kableExtra. But stuff like $Y_{t-1}$ or $p < .001$ (since I want the p to be italic) does not work. Or should I really learn xtable? 回答1: The trick is 1. to escape latex code and special characters four times, e.g. \\\\frac , 2. to set option escape=FALSE in footnote() . --- title: "Untitled" output: pdf_document --- ```{r tab}

问题 I'm developing a JAVA program which processes the XML content of docx files and converts it to a specific format. It's working quite well, but I have problems if the Word file contains Symbol characters e.g. greek letters. In this case I see only little squares. I checked the source and see something like this: <w:r w:rsidRPr="008E65F6"><w:rPr><w:rFonts w:ascii="Symbol" w:hAnsi="Symbol"/></w:rPr><w:t>ďˇ</w:t></w:r> Or if I set the encoding to UTF-8: <w:r w:rsidRPr="008E65F6"><w:rPr><w:rFonts

问题 I have recently begun using Scala. I've written a DSL in it which can be used to describe a processing pipeline in medici. In my DSL, I've made use of symbols to signify an anchor, which can be used to put a fork (or a tee, if you prefer) in the pipeline. Here's a small sample program that runs correctly: object Test extends PipelineBuilder { connector("TCP") / Map("tcpProtocol" -> new DirectProtocol()) "tcp://localhost:4858" --> "ByteToStringProcessor" --> Symbol("hello") "stdio://in

问题 I'm making a calculator in javascript and as of now it calculates: sin , cos , tan , cot , sec , csc and also arc and hyberbolic of all subtypes, sqrt , cbrt , y-th root , and pow . The problem is that I dont want to have the pow(x,y) as a function, I want to be able to type in for example: 2^3+2^4 # instead of pow(2,3)+pow(2,4) How do I go about to get the function typed in as shown above? Here's the calculator for viewing it: http://calcy.comze.com/ 回答1: I assume you have the formula in a

问题 I saw there are other questions about the dot "." I followed but it didn't work for my code.... it's a part of code, the implementation is not focused to this symbol. but output should be included this dot. when I give input of two lists '(1 2 3) '(4 5) my expected output => (1 . 4) (2 . 5) I managed to get (1 4) (2 5) just need to add "." in the middle. Part of mycode (cons (list (car lst1) (car lst2)) .... for the "." symbol , if I try **trial-1** (cons '(list (car lst1) (car lst2)) ...)

问题 I just updated tensorflow with pip3 (now to version 1.4.1). After it I am having problems: I have a custom op library that I compile with -D _GLIBCXX_USE_CXX11_ABI=0. The library compiles and links fine. Importing it into tensorflow gives: Traceback (most recent call last): ... File "../x.py", line 29, in <module> lib = tf.load_op_library(_lib_path) File "/home/ilge/.local/lib/python3.5/site-packages/tensorflow/python/framework/load_library.py", line 56, in load_op_library lib_handle = py_tf

问题 An application ( app ) depends on two shared librarys: liba.so and libb.so . liba and libb have the same function of void Hello() but with different implementations. Load the two shared libraries at runtime and try to access the two versions of Hello(). I load liba.so and libb.so by poco C++ shared-library, but eventually it calls dlopen() to load shared libraries. Here's the code: #include "Poco/SharedLibrary.h" using Poco::SharedLibrary; typedef void (*HelloFunc)(); // function pointer type

问题 It's cool that Rebol's PARSE dialect is generalized enough that it can do pattern matching and extraction on symbolic structures as well as on strings. Like this: ; match a single "a" character, followed by any number of "b" chars >> string-rule: ["a" some "b"] >> parse "abb" string-rule == true >> parse "aab" string-rule == false ; look for a single apple symbol, followed by any number of bananas >> block-rule: ['apple some 'banana] >> parse [apple banana banana] block-rule == true >> parse

问题 There are 25 symbols defined by 'pch' paramter in the points function. How can I draw more than these 25 symbols Thanks 回答1: You can see all the options for a given font using code like: plot( 0:15, 0:15, type='n' ) points( (0:255)%% 16, (0:255) %/% 16, pch=0:255, font=5 ) Change the font= to different numbers for different options. There are a couple more options using the symbols function. If you want even more then check out the my.symbols function in the TeachingDemos package (I am the
