Managing VB2010 Data 
 Getting to know various data types in Visual Basic 2010 
 Assigning values to the variables 
 Getting to know various arithmetic operators in Visual Basic 2010 
In our daily life we come across many types of data. For example, we need to handle data 
such as names, addresses, money, dates, stock quotes, statistics and more everyday. 
Similarly, in Visual Basic 2010, we have to deal with all sorts of data; some are numeric in 
natrure while some are in the form of text or other forms. VB2010 divides data into different 
types so that it is easier to manage when we need to write the code involving those data. 
4.1 Visual Basic 2010 Data Types
Visual Basic classifies the information mentioned above into two major data types; namely 
the numeric data types and the non-numeric data types. 
4.1.1 Numeric Data Types 
Numeric data types are types of data that consist of numbers, which you can compute 
them mathematically with various standard operators such as add, minus, multiply, divide 
and so on. Examples of numeric data types are your examination marks, your height and 
your weight, the number of students in a class, share values, price of goods, monthly bills, 
fees and more. In Visual Basic 2010, we divide numeric data into seven types, depending 
on the range of values they can store. Calculations that only involve round figures or data 
that do not need precision can use Integer or Long integer in the computation. Programs 
that require high precision calculation need to use Single and Double decision data types, 
we also call them floating-point numbers. For currency calculation, you can use the .
Summary 
 In section 4.1, you learned that we could categorize data types into numeric and 
non-numeric data types. 
 In section 4.2, you learned about the rules to name variables in Visual Basic 
2010. Besides, you also learned how to declare variables using the Dim keyword 
and assign values to them. 
 In section 4.3, you learned about constants and the way to declare them.

Module 5

Computers can perform mathematical calculations much faster than human beings.  However, the computer itself will not be able to perform any mathematical calculations  without receiving instructions from the programmer. In VB2010, we can write code to  instruct the computer to perform mathematical calculations such as addition, subtraction,  multiplication, division and other kinds of arithmetic operations. In order for VB2010 to  carry out arithmetic calculations, we need to write code that involves the use of various  arithmetic operators. The VB2010 arithmetic operators are very similar to the normal  arithmetic operators, only with slight variations. The plus and minus operators are the  same while the multiplication operator use the * symbol and the division operator use the /  symbol. The list of VB2010 arithmetic operators are shown in table 5.1 below: Summary  In this chapter, you learned how to use various mathematical operators...

A function is similar to a normal procedure but the main purpose of the function is to accept  a certain input and return a value, which is passed on to the main program to finish the  execution. There are two types of functions, the built-in functions (or internal functions) and  the functions created by the programmers.  The general format of a function is   FunctionName (arguments)  The arguments are values that are passed on to the function.  In this Chapter, we are going to learn two very basic but useful internal functions of Visual  Basic, i.e. the MsgBox( ) and InputBox ( ) functions.  Summary  You learned that a function is a procedure that accepts an input and returns a value,  which is passed on to the main program to finish the execution. You also learned  that the format of a function is FunctionName (arguments).  In section 10.1, you learned to use the Msg () function to produce a popup  message box...
