The int type (short for integer) represents whole numbers. That s clearly no use for our example, because we re dealing with numbers such as 5.14, and the closest that an int can get to that value is 5. But programs often deal with discrete quantities, such as the number of rows returned by a database query or the number of employees reporting to a particular manager. The principal advantage of an integer type is that it s exact: there s no scope for wondering if the number is really 5, or maybe just a number quite close to 5, such as 5.000001. Table 2-1 lists nine types capable of representing integers. The ninth, BigInteger, is a special case that we ll get to later. The other eight support four different sizes, with a choice between the ability and inability to represent negative numbers. Unsigned numbers may seem less flexible, but they are potentially useful if you need to represent values that should never be negative. However, the unsigned integer types are not widely used some programming languages don t support them at all, and so you ll find that the .NET Framework class library tends to use the signed types even

when the unsigned ones might make more sense. For example, the Count property available on most collection types is of type int a signed 32-bit integer even though it does not make sense for a collection to contain a negative number of items.

Unsigned integers can also represent larger numbers than their signed equivalents. They don t need to use up a bit to represent the sign, so they can use that to extend the range instead. However, this is something you should be wary of depending on. If you re so close to the limits of a type s range that one more bit makes a difference, you re probably in danger of overflowing the type s range in any case, and so you should consider a larger type.

Besides the signed/unsigned distinction, the various types offer different sizes, and a correspondingly different range of values. 32 bits is a popular choice because it offers a usefully wide range of values and is efficient for a 32-bit processor to work with. 64bit types are used for the (fairly rare) occasions when you re dealing with large enough quantities that a 32-bit representation s range of a couple of billion is insufficient. 16bit values are rarely used, although they occasionally crop up when having to deal with old programming interfaces, file formats, or network protocols. The 8-bit byte type is important because binary I/O (e.g., working with files or network connections) is mostly byte-oriented. And for reasons of historical convention, bytes buck the trend in that the unsigned type is used more widely than the signed sbyte type. But outside of I/O, a byte is usually too small to be useful. So in practice, int is the most widely used integer type. The fact that C# even offers you all these other choices can seem a little archaic it harks back to the time when computers had so little memory that 32-bit numbers looked like an expensive choice. It gets this from its C-family connections, but it does turn out to be useful to have this control when you need to work directly with Windows APIs, as you ll see in 19. Notice that most of the types in Table 2-1 have two names. C# uses names such as int and long, but the .NET Framework calls these types by longer names such as System.Int32 and System.Int64. The shorter C# names are aliases, and C# is happy to let you use either. You can write this:

All of these are equivalent they produce exactly the same compiled output. The last two are equivalent simply because of how namespaces work, but why does C# support a completely different set of aliases The answer is historical: C# was designed to be easy to learn for people who are familiar with the so-called C family of languages, which includes C, C++, Java, and JavaScript. Most of the languages in this family use the same names for certain kinds of data types most use the name int to denote a conveniently sized integer, for example. So C# is merely following suit it allows you to write code that looks like it would in other C-family languages. By contrast, the .NET Framework supports many different languages, so it takes the prosaic approach of giving these numeric data types descriptive names it calls a 32bit integer System.Int32. Since C# lets you use either naming style, opinion is divided on the matter of which you should use. The C-family style (int, double, etc.) seems to be the more popular. Version 4 of the .NET Framework introduces an extra integer type that works slightly differently from the rest: BigInteger. It does not have a C-style name, so it s known only by its class library name. Unlike all the other integer types, which occupy a fixed amount of memory that determines their range, a BigInteger can grow. As the number it represents gets larger, it simply consumes more space. The only theoretical limit on range is the amount of memory available, but in practice, the computational cost of working with vast numbers is likely to be the limiting factor. Even simple arithmetic operations such as multiplication can become rather expensive with sufficiently vast numbers. For example, if you have two numbers each with 1 million decimal digits each number occupies more than 400 kilobytes of memory multiplying these together takes more than a minute on a reasonably well-specified computer. BigInteger is useful for mathematical scenarios when you need to be able to work with very large numbers, but in more ordinary situations, int is the most popular integer type. Integers are all very well for countable quantities, but what if you need the ability to represent something other than a whole number This is where floating-point types come in.
