I have a situation where I need to display a double value rounded to two decimal places, but displayed without the decimal. There will be some situations where I will want to use the same code and display the double value differently, so I was hoping I could handle this by passing in a string format pattern. For example, the double val...
I have some issues with number <-> string conversion i cannot sort out. We have written a serialization framework which uses several xml serialization techniques. But i have seen some inconsistent number conversions in the generated output: using: var c = TypeDescriptor.GetConverter(double); var s = c.ConvertToString(value); and va...
Can Javascript get a function as text? I'm thinking like the inverse of eval(). function derp() { a(); b(); c(); } alert(derp.asString()); The result would be something like "a(); b(); c();" Does it exist? ...
Just curious if anyone has any opinions on throwing an exception in my overridden ToString implementation. My instincts tell me this might be bad practice, but I don't seem to be able to find anything supporting if this is bad or not. Any thoughts? Code: http://pastebin.com/mLEkBAAz Thanks. ...
I get this when I call toString on an object I received from a function call. I know the type of the object is encoded in this string, but I don't know how to read it. What is this type of encoding called? ...
var bytes:ByteArray = new ByteArray; bytes.writeInt(0); trace(bytes.length); // prints 4 trace(bytes.toString().length); // prints 4 When I run the above code the output suggests that every character in the string returned by toString contains one byte from the ByteArray. This is of course great if you want to display the content of t...
I have an ArrayList of User objects. Now I need the ArrayList of these user's names only. Is there a way to use toString() on entire ArrayList and convert it to ArrayList of String names rather than doing this in for loop? I have also overridden toString in User class so it returns user's name, and I have tried ArrayList <String> names =...

I'm after line by line annotations: template<class T> string toString(const T& t, bool *ok = NULL) { ostringstream stream; stream << t; if(ok != NULL) *ok = stream.fail() == false; return stream.str(); } Is it like Java's toString() method? ...

Bloch said: Provide Programmatic Access to All Data Available in String Form. I am wondering if he means to override toString() which should involve 'all data available'? I think the 'in string form' means that the string is for human reading, so override toString() is enough for the advice. Am I correct? ...
We use __toString() to returning class's default value like that: <?php class my { public function __toString() { return "asdasd"; } } ?> It returns only string type. But I want to return resource type: <?php class my { public function __toString() { return imagecreatefromjpeg("image.jpg"); } } ?> ...
I've got the following enum: public enum myEnum { ONE("ONE"), TWO("TWO"); private String name; private myEnum(String name) { this.name = name; } @Override public String toString() { return name; } }; My question is why does the following evaluate to false? I suspect it has something to do...
According to the tool PMD, the following is a bad practice: String s = "" + 123; // bad String t = Integer.toString(456); // ok This is an inefficient way to convert any type to a `String`. Why is it a bad thing to do? ...
I have a strange business requirement to output dates as 01:00 through 24:00, instead of the usual 00:00 through 23:00. It is really a crazy requirement, but unfortunately I don't think I can avoid it. This will be a configuration option in our software, so I'll still need to support the normal 00-23 as well, so I'm hoping I can do thi...

How come Object.prototype.toString === toString? If I have this in the global scope: var toStringValue = toString.call("foobaz"); I would expect toStringValue to be the value of window.toString because window is the default scope, right? How come toString by itself resolves to Object.prototype.toString instead of window.toString? ...
(deftype Bag [state] Object (toString [bag] (str "Bag???" state))) I want the toString to look something like clojure.core=> (def b (Bag. {:apples 1 :bannanas 4})) #'clojure.core/b clojure.core=> (str b) "BAG: {:apples 1 :bannanas 4}" What is a nice clojurey way of representing that information? Is "Bag/{:k :v}" ...
