Perhaps the most interesting C# numeric type is decimal, which is intended for use in monetary calculations The decimal type utilizes 128 bits to represent values within the range 1E 28 to 79E+28 As you may know, normal floating-point arithmetic is subject to a variety of rounding errors when it is applied to decimal values The decimal type eliminates these errors and can accurately represent up to 28 decimal places (or 29 places in some cases) This ability to represent decimal values without rounding errors makes it especially useful for computations that involve money Here is a program that uses a decimal type in a financial calculation The program computes the discounted price given the original price and a discount percentage

In the program, notice that the decimal constants are followed by the m suffix This is necessary because without the suffix, these values would be interpreted as standard floating-point constants, which are not compatible with the decimal data type You can assign an integer value, such as 10, to a decimal variable without the use of the m suffix, though (A detailed discussion of numeric constants is found later in this chapter) Here is another example that uses the decimal type It computes the future value of an investment that has a fixed rate of return over a period of years

static void Main() { decimal amount; decimal rate_of_return; int years, i; amount = 10000M; rate_of_return = 007M; years = 10; ConsoleWriteLine("Original investment: $" + amount); ConsoleWriteLine("Rate of return: " + rate_of_return); ConsoleWriteLine("Over " + years + " years"); for(i = 0; i < years; i++) amount = amount + (amount * rate_of_return); ConsoleWriteLine("Future value is $" + amount); } }
PART I
Here is the output:
Original investment: $1000 Rate of return: 007 Over 10 years Future value is $1967151357289565322490000
Notice that the result is accurate to several decimal places more than you would probably want! Later in this chapter you will see how to format such output in a more appealing fashion
Characters
In C#, characters are not 8-bit quantities like they are in many other computer languages, such as C++ Instead, C# uses a 16-bit character type called Unicode Unicode defines a character set that is large enough to represent all of the characters found in all human languages Although many languages, such as English, French, and German, use relatively small alphabets, some languages, such as Chinese, use very large character sets that cannot be represented using just 8 bits To address this situation, in C#, char is an unsigned 16-bit type having a range of 0 to 65,535 The standard 8-bit ASCII character set is a subset of Unicode and ranges from 0 to 127 Thus, the ASCII characters are still valid C# characters A character variable can be assigned a value by enclosing the character inside single quotes For example, this assigns X to the variable ch:
char ch; ch = 'X';
You can output a char value using a WriteLine( ) statement For example, this line outputs the value in ch:
ConsoleWriteLine("This is ch: " + ch);

The C# Language
Although char is defined by C# as an integer type, it cannot be freely mixed with integers in all cases This is because there are no automatic type conversions from integer to char For example, the following fragment is invalid:
