Next is an example that uses the Pow( ) method to compute the initial investment required to achieve a desired future value given the annual rate of return and the number of years The formula to compute the initial investment is shown here: InitialInvestment = FutureValue / (1 + InterestRate)Years

Code128 Encoder In Java
Using Barcode creation for Java Control to generate, create USS Code 128 image in Java applications.
Part II:
Exploring the C# Library
Because Pow( ) requires double arguments, the interest rate and the number of years are held in double values The future value and initial investment use the decimal type
/* Compute the initial investment needed to attain a known future value given annual rate of return and the time period in years */ using System; class InitialInvestment { static void Main() { decimal initInvest; // initial investment decimal futVal; // future value double numYears; double intRate; string str; ConsoleWrite("Enter future value: "); str = ConsoleReadLine(); try { futVal = DecimalParse(str); } catch(FormatException exc) { ConsoleWriteLine(excMessage); return; } ConsoleWrite("Enter interest rate (such as 0085): "); str = ConsoleReadLine(); try { intRate = DoubleParse(str); } catch(FormatException exc) { ConsoleWriteLine(excMessage); return; } ConsoleWrite("Enter number of years: "); str = ConsoleReadLine(); try { numYears = DoubleParse(str); } catch(FormatException exc) { ConsoleWriteLine(excMessage); return; } initInvest = futVal / (decimal) MathPow(intRate+10, numYears); ConsoleWriteLine("Initial investment required: {0:C}", initInvest); } } // number of years // annual rate of return as a decimal

The NET Structures Corresponding to the Built-in Value Types
The structures that correspond to C# s built-in value types were introduced in 14 when they were used to convert strings holding human-readable numeric values into their equivalent binary values Here these structures are examined in detail The NET structure names and their C# keyword equivalents are shown in the following table:
NET Structure Name SystemBoolean SystemChar SystemDecimal SystemDouble SystemSingle SystemInt16 SystemInt32 SystemInt64 SystemUInt16 SystemUInt32 SystemUInt64 SystemByte SystemSByte C# Name bool char decimal double float short int long ushort uint ulong byte sbyte
PART II
By using the members defined by these structures, you can perform operations relating to the value types The following sections examine each of these structures
NOTE Some methods defined by the structures that correspond to the built-in value types take a
parameter of type IFormatProvider or NumberStyles IFormatProvider is briefly described later in this chapter NumberStyles is an enumeration found in the SystemGlobalization namespace The topic of formatting is discussed in 22
The Integer Structures
The integer structures are
Byte Int32 SByte UInt32 Int16 Int64 UInt16 UInt64
Part II:
Exploring the C# Library
Each of these structures contains the same methods They are shown in Table 21-2 The only difference from structure to structure is the return type of Parse( ) For each structure, Parse( ) returns a value of the type represented by the structure For example, for Int32, Parse( ) returns an int value For UInt16, Parse( ) returns a ushort value For an example that demonstrates Parse( ), see 14 In addition to the methods shown in Table 21-2, the integer structures also define the following const fields: MaxValue MinValue For each structure, these fields contain the largest and smallest value that type of integer can hold All of the integer structures implement the following interfaces: IComparable, IComparable<T>, IConvertible, IFormattable, and IEquatable<T>, where T is replaced by the corresponding data type For example, T will be replaced with int for Int32
Method public int CompareTo(object v) Meaning Compares the numerical value of the invoking object with that of v Returns zero if the values are equal Returns a negative value if the invoking object has a lower value Returns a positive value if the invoking object has a greater value Compares the numerical value of the invoking object with that of v Returns zero if the values are equal Returns a negative value if the invoking object has a lower value Returns a positive value if the invoking object has a greater value In this version of CompareTo( ), type explicitly specifies the data type, such as in SystemInt32CompareTo(int v) Returns true if the value of the invoking object equals the value of v Returns true if the value of the invoking object equals the value of v In this version of Equals( ), type explicitly specifies the data type, such as in SystemInt32Equals(int v) Returns the hash code for the invoking object Returns the TypeCode enumeration value for the equivalent value type For example, for Int32, the type code is TypeCodeInt32 Returns the binary equivalent of the numeric string in str If the string does not represent a numeric value as defined by the structure type, an exception is thrown retType is a placeholder for the actual type of data returned based on which numeric structure is used For example, for Int32, retType will be int
public int CompareTo(type v)
public override bool Equals(object v) public bool Equals(type v)
public override int GetHashCode( ) public TypeCode GetTypeCode( )
public static retType Parse(string str)
