string-conversion

In my locale the decimal separator is a ','. However I would still like to write a C# application which works with numbers that use the '.' as decimal separator. string b = "0,5"; double db = double.Parse(b); // gives 0.5 string a = "0.5"; double da = double.Parse(a); // gives 5, however i would like to get 0.5 You need to specify the culture as the second argument to double.Parse , e.g. double da = double.Parse(a, CultureInfo.InvariantCulture); Pretty much all of the formatting/parsing methods have overloads taking an IFormatProvider , and the most commonly-specified implementation of

I wrote the following code to check whether the input(answer3) is a number or string, if it is not a number it should return "Enter Numbers Only" but it returns the same even for numbers. Please suggest me a solution. #include <iostream> #include <string> #include <typeinfo> #include <stdio.h> #include <stdlib.h> #include <ctype.h> using namespace std; int main () { string ques1= "Client's Name :"; string ques2 = "Client's Address :"; string ques3 = "Mobile Number :"; char answer1 [80]; string answer2; int answer3; cout<<ques1<<endl; cin>>answer1; cout<<ques2<<endl; cin>>answer2; cout<<ques3<

What is the difference between parseInt(string) and Number(string) in JavaScript has been asked previously. But the answers basically focused on the radix and the ability of parseInt to take a string like "123htg" and turn it into 123 . What I am asking here is if there is any big difference between the returns of Number(...) and parseFloat(...) when you pass it an actual number string with no radix at all. James Allardice No. Both will result in the internal ToNumber(string) function being called. From ES5 section 15.7.1 (The Number Constructor Called as a Function): When Number is called as

What is a function in PHP used to convert array to string, other than using JSON? I know there is a function that directly does like JSON. I just don't remember. serialize() is the function you are looking for. It will return a string representation of its input array or object in a PHP-specific internal format. The string may be converted back to its original form with unserialize() . But beware, that not all objects are serializable, or some may be only partially serializable and unable to be completely restored with unserialize() . $array = array(1,2,3,'foo'); echo serialize($array); //

I am working on an Android application. In my app I have to convert a string to Json Object, then parse the values. I checked for a solution in stackoverflow and found similar issue here link The solution is like this `{"phonetype":"N95","cat":"WP"}` JSONObject jsonObj = new JSONObject("{\"phonetype\":\"N95\",\"cat\":\"WP\"}"); I use the same way in my code . My string is {"ApiInfo":{"description":"userDetails","status":"success"},"userDetails":{"Name":"somename","userName":"value"},"pendingPushDetails":[]} string mystring= mystring.replace("\"", "\\\""); And after replace I got the result as
