Integral Types in C Sharp

by Dinesh 2012-07-22 20:19:43

In C#, an integral is a category of types. For anyone confused because the word Integral sounds like a mathematical term, from the perspective of C# programming, these are actually defined as Integral types in the C# programming language specification. They are whole numbers, either signed or unsigned, and the char type. The char type is a Unicode character, as defined by the Unicode Standard.

The Size and Range of C# Integral Types

Type Size (in bits) Range

sbyte 8 -128 to 127
byte 8 0 to 255
short 16 -32768 to 32767
ushort 16 0 to 65535
int 32 -2147483648 to 2147483647
uint 32 0 to 4294967295
long 64 -9223372036854775808 to 9223372036854775807
ulong 64 0 to 18446744073709551615
char 16 0 to 65535

Integral types are well suited for those operations involving whole number calculations. The char type is the exception, representing a single Unicode character. As you can see from the table above, you have a wide range of options to choose from, depending on your requirements.
