The Convert class has an overload of the static ToString() method that takes two ints and returns a string populated with the number in the specified base. For instance, calling Convert.ToString(128, 2) will return "10000000".

Perhaps the universe strives for multiplicity. Perhaps that is its end and completion...the Many are at least as real as the One. Probably more so in fact. See similar questions...

You want to make a function that converts from a type to another. Like from std::string to int, or the other way around. This can be done using std::stringstream and insertion / extraction operators. Just as above, templates will prove of great help: Its usage is not as straightforward as the above explained max template. Normally, you would want to call it like "int value = lexical_cast( myStdString );". There is, however, a problem. See similar questions...

To work out what title was Number 1 on the day on which you were born it is necessary to know when the chart was actually disclosed. The week-ending date does not help here. However, our date engine knows when each chart was unveiled. This will automatically give you an accurate answer to the real Number 1 for any given date. See similar questions...

In general, when you want to convert from one type to another, the first class to look at is System.Convert. It has a load of static methods which are likely to help you. If you're converting from a String, you could also check whether the type that you want to convert to has a Parse method or something similar - for instance, I usually use DateTime.ParseExact to convert from a String to a DateTime.

There are several ways. The most straightforward is: String myString = numString.trim(); int i = Integer.parseInt(myString); long l = Long.parseLong(myString) or String myString = numString.trim(); i = Integer.parseInt(myString,myIntRadix); Note 1: There is a gotcha with parseInt - it will throw a NumberFormatException for String values in the range "80000000" to "ffffffff". You might expect it to interpret them as negative, but it does not. The values have to be "-80000000" . See similar questions...

Try any of these: String s = String.valueOf(i); or String s = Integer.toString(i); or String s = Integer.toString(i, radix); or // briefer but may result in extra object allocation. String s = "" + i; Note: There are similar classes for Double, Float, Long, etc. See similar questions...

I am including the header file <string>, and I am using the string class, but the code doesn't compile? (namespace resolution, having the std:: topics) How do I use unique() with vectors? (answered only once, but still a good question to have due to people not knowing that it's possible to do) See similar questions...

The easiest way is to pick up the source for the 100% pure Java class EasyIn from http://www.afu.com/ (same place as this FAQ) Compile it with your code and use it like this: EasyIn easy = new EasyIn(); int i = easy.readInt(); // gets an int from System.in boolean b = easy.readBoolean(); // gets a boolean from System.in double d = easy.readDouble(); // gets a double from System.in ... etc. See similar questions...

How to add a float (or "any" type really) to the end of a C++ string? Unlike routines like atoi mentioned in the previous question, there is no direct routine such as itoa available. However, similar to the string I/O routines in the previous question, one can do this: #include <stdio.h> // cstdio in C++ // .. See similar questions...

You use static members of the Convert class found in the System namespace to handle conversions in the .NET framework. See similar questions...

This is something you do a lot in programming and pretty much every language makes it easy to convert between types. You may have already printed integers to the console with COUT or PRINTF, which of course needs to be converted to a string first. Converting numbers to strings is done in a similar way. Boost is a C++ library that can help you with problems like these and many others. See similar questions...

There are two easy ways to do this: you can use the <cstdio> facilities or the <iostream> library. In general, you should prefer the <iostream> library. See similar questions...

Yes, varchars have no intrinsic size limit and can be used to store marshalled or pickled Python BLOBS -- but the application using gadfly will have to know when to "deserialize" the objects (using marshal or pickle or other mechanisms). For example it is even possible to store Python byte code objects in a gadfly database in this way. See similar questions...

There are a number of ways, with varying efficiency. If you want a count of a certain single character (X) within a string, you can use the "tr///" function like so: $string = "ThisXlineXhasXsomeXx'sXinXit"; $count = ($string =~ tr/X//); print "There are $count X characters in the string"; This is fine if you are just looking for a single character.
