Editor to share with you what data types VB.NET has, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

VB.NET data type

There are 12 different data types in VB.NET, which can be divided into three categories: numeric type, text type, and mixed type. Numeric types are the main types of VB.NET data types, with a total of 7. The data types of numeric types are shown in the table below.

Data type

Mode of representation

Take value norm circumference

Make it clear

Integer type

Integer

-21474836481147483647

Used to represent simple integers

Byte type

Byte

08255

Used for simple arithmetic operations. Since this type of variable can be stored in one byte, the operation is the fastest.

Short integer type

Short

-32768mm 32767

Is a form of integer with a relatively small range of representation

Long integer type

Long

-9223372036854775808 ~

9223372036854775807

It is a form of integer and has a relatively wide range of representation.

Single essence

Degree type

Single

-3.402823E38~-1.401298E-45 (for negative numbers) and 1.401298E-45~3.402823E38 (for positive numbers)

Used to store single-precision floating point numbers

Double essence

Degree type

Double

-1.79869313486232E308~

-4.94065645841247E-324 (for negative numbers)

And 4.94065645841247E muri 324~

1.79869313486232E308 (for positive numbers)

Used to store double-precision floating point numbers

Decimal number

Decimal

When the decimal place is 0,

-79228162514264337593543950335 ~

79228162514264337593543950335

When the decimal place is 28,

-7.9228162514264337593543950335 ~

7.9228162514264337593543950335

Often used to store monetary values

Data type of numeric type

There are two data types for storing text. The VB.NET data type of the text type is shown in the following table.

Data type

Table formula

State clearly

String type

String

Used to store any form of string, including one character or multiple lines of characters

Character type

Char

Used to store a character that is stored as a number between 0mm 65535

Data type of text type

What needs to be explained is:

(1) for String type, you can store any form of string, which can be pure text, a combination of text and numbers, numbers, dates, and so on. For example, "This is a book." and "12345" are strings. For string type data, you can perform related string operations, such as concatenation, truncation, and so on.

(2) for the Char type, only one character can be stored. Note that the storage code for this character must be a number. In a computer system, many symbols can be displayed (not just the English alphabet). In order to display correctly, there are international standards (such as Unicode coding) that set a standard value for each character to represent the character. The remaining data types include the Date data type, the Boolean data type, and the Object data type, as described in the table below.

Data type

Table formula

State clearly

Date type

Date

Must be expressed in mm/dd/yyyy format, or you can store time (can store any time between 0015, 0012, 23, 23, 59 and 59)

Boolean type

Boolean

Values are True and False

Object type

Object

Other data types

It should be noted that in VB.NET, for data of type Boolean, when the value of Boolean type needs to be converted to a numerical type, True will be treated as 1 and False as 0. When you need to convert a value of the VB.NET numeric type to a Boolean type, it converts 0 to False and other non-zero values to True.

The above is all the content of the article "what are the data types of VB.NET". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
