Data Types in LightSwitch

Introduction

Data Type is the type of data in the programming. They have predefined characteristics. When a program stores the data in a variable then each variable must be assigned a specific type of data. Some common data type is integer, float, string etc.

Classes of data types

There are many types of classes of data types, which are as follows.

Binary data type
Boolean data type
Numeric data type
String data type
Date & Time data type
TimeSpan data type

Binary Data type

In the binary data type you can store any type of binary data Binary data is row data. There are many types of binary data, Which are as follows

Byte data type

VB Type : Byte()
C# Type : byte[]
Range : True or False
Remark : An array of bytes that has a variable length

Image data type

VB Type : Byte()
C# Type : byte[]
Range : No
Remark : A Binary treated as a image

Boolean data type

There are two values in Boolean data type which are 'true' & 'false'. There are only two value possible i.e.' true' & 'false'. The Boolean data type also implement as 0 & 1.The meaning of 0 is false and 1 is true.

VB Type : Boolean
C# Type : bool
Range : 0 to 255

Numeric data type

There are many numeric data types in LightSwitch. Which are as follows

Integer data type
Float data type

Integer data type

Short Integer

VB Type : Short
C# Type : short
Range : -32768 to 32767
Remark : A signed 16-bit integer

Integer

VB Type : Integer
C# Type : int
Range : -32768 to 32767
Remark : A signed 32-bit integer

Long Integer

VB Type : Long
C# Type : long
Range : -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
Remark : A signed 64-bit integer

Float data type

Double

VB Type :Double
C# Type : double
Range : +-5.0e-324 to +-1.7e+308
Remark : Floating decimal point with 16-16 digits precision, suitable for scientific number

Decimal

VB Type : Decimal
C# Type : decimal
Range : +-1.0e-28 to +-7.9e28
Remark : Fixed decimal point value with 28-29 significant digits, suitable for financial and monetary values, stored with specific precision and scale

Single

VB Type : Single
C# Type : float
Range : +-1.5e-45 to +-3.4e+38
Remark : Floating decimal point with 7 digits precision

Money

VB Type : Decimal
C# Type : decimal
Range : No
Remark : A Decimal treated as a monetary value

String data type

String is a set of characters or sequence of character. Which are typically used to represent words and text. There are three string type in LightSwitch, Which are as follows

String

VB Type : String
C# Type : string
Range : A sequence of zero or more Unicode characters
Remark : A set of character that has variable length

PhoneNumber

VB Type : String
C# Type : string
Range : No
Remark : A string treated as a phone number

EmailAddress

VB Type : String
C# Type : string
Range : No
Remark : A string treated as a email address

Date & Time data type

Date and Time data types are used for values which contain date and time.The date data type is used to specify a date and time data type is used to specify time.

VB Type : Date
C# Type : DateTime
Range : 00:00:00 Jan 1,0001 AD(CE) to 23:59:59 Dec 31,9999 AD(CE)

TimeSpan data type

A TimeSpan data type is a difference between the two DateTime data type.

VB Type : TimeSpan
C# Type : TimeSpan
Range : 00:00:00:000000 to 23:59:59:9999999
Remark : A time interval in days, hours, minutes, second and fraction of second

Summary

So data type is a type of data which is used in the programming. It is very necessary for declare the variable before using it.
