We have three important floating point types: Single,ĭouble, and Decimal. Measure continuous quantities, like weight, height, or speed. $ dotnet runįloating point numbers represent real numbers in computing. The Short data type is big enough to count our apples. Dim total As Short = baskets * applesinbasket In our program, we count the total amount of apples. They are written without aįraction or a decimal component. Integers are a subset of the real numbers. If/Else statements work with Boolean values. If the male variable is set to True, we choose name John. If num = 0 Thenĭepending on the num variable, the Boolean male The Randomize function initializes a random-number generator The Double data type is converted into Byte using theĬType function. All other random values are rounded to 0. Random values greater than 0.5Īre rounded to 1. Random value less than 1, but greater than or equal to zero. The program uses a random number generator to simulate our case. If it is goingĬonsole.WriteLine("We will use name John")Ĭonsole.WriteLine("We will use name Jessica") If it is going to be a boy, they have chosen John. Happy parents are waiting a child to be born. In Visual Basic theīoolean data type is a primitive data type having one of two Jing and jang, man and woman, love and hatred. There is a Heaven and Earth, water and fire, ForĮxample, boolean default value is False, decimal 0, string an empty string "". Value types have different default values. Assignment to a variable of a value type creates aĬopy of the value being assigned. The reference rather than a copy of the referenced value. Assignment to a variable of a reference type creates a copy of Classes, strings, standard modules, interfaces, arrays, and delegates are Primitive types (except strings), enumerations, and structures are value The two fundamental data types in Visual Basic are value types and reference According to the Wikipediaĭefinition, a data type is a set of values, and the allowable Tools to work with various data types areĮssential part of a modern computer language. In this part of the Visual Basic tutorial, we talk about data types.Ĭomputer programs work with data. Contents Previous Next Visual Basic data types
