Datatype Conversion

/**
 * Datatype Conversion. 
 * 
 * It is sometimes beneficial to convert a value from one type of 
 * data to another. Each of the conversion functions converts its parameter 
 * to an equivalent representation within its datatype. 
 * The conversion functions include int(), float(), char(), byte(), and others.
