C# Tutorial , Step-5, Built in Data Types

 Hello, Welcome to all. My name is Abdul Yesdani. Today we are going to learn about built in data types of C# language.

The following list describe the C# built in types.

Integral numeric types
Type	Description / Range
bool	True or false
byte	0-255     Unsigned 8 bit integer
sbyte	-128 to 127       Signed 8 bit integer
short	-32,768 to 32,767         Signed 16-bit integer
ushort	0 to 65,535               Unsigned 16-bit integer
int	-2,147,483,648 to 2,147,483,647    Signed 32-bit integer
uint	0 to 4,294,967,295     Unsigned 32-bit integer
long	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Signed 64-bit integer
ulong	0 to 18,446,744,073,709,551,615 Unsigned 64-bit integer
Floating Types
float	±1.5 x 10−45 to ±3.4 x 1038             4 bytes
double	±5.0 × 10−324 to ±1.7 × 10308        8 bytes
decimal	±1.0 x 10-28 to ±7.9228 x 1028       16 bytes
Other Types
bool	Represents true or false
char	Represents a Unicode UTF-16 character.
String	Reference a sequence of zero or more Unicode UTF-16 characters.

We can use any of above types as variable types in our program code as per need.

Example : float  price=67855.78

                  double rate_item = 4535566.89999

                   int num=8900

                   char  letter = 'T'

                  string person ="Noah"
