Integer ranges
In this chapter you will learn:
C# Integer ranges
| Type | Size | Range (Inclusive) | BCL Name | Signed |
|---|---|---|---|---|
| sbyte | 8 bits | -128 to 127 | System.SByte | Yes |
| byte | 8 bits | 0 to 255 | System.Byte | No |
| short | 16 bits | -32,768 to 32,767 | System.Int16 | Yes |
| ushort | 16 bits | 0 to 65,535 | System.UInt16 | No |
| int | 32 bits | -2,147,483,648 to 2,147,483,647 | System.Int32 | Yes |
| uint | 32 bits | 0 to 4,294,967,295 | System.UInt32 | No |
| long | 64 bits | -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 | System.Int64 | Yes |
| ulong | 64 bits | 0 to 18,446,744,073,709,551,615 | System.UInt64 | No |
The following code prints out the range of integer types in C#.
using System;//from j a va2 s . c o m
using System.Collections.Generic;
using System.Globalization;
using System.IO;
using System.Text;
using System.Security.Cryptography;
public class MainClass
{
public static void Main()
{
Console.WriteLine("{0}: bytes: {1}, range: [{2},{3}]",
typeof(byte).ToString(), sizeof(byte), byte.MinValue, byte.MaxValue);
Console.WriteLine("{0}: bytes: {1}, range: [{2},{3}]",
typeof(char).ToString(), sizeof(char), (int)char.MinValue, (int)char.MaxValue);
Console.WriteLine("{0}: bytes: {1}, range: [{2},{3}]",
typeof(short).ToString(), sizeof(short), short.MinValue, short.MaxValue);
Console.WriteLine("{0}: bytes: {1}, range: [{2},{3}]",
typeof(int).ToString(), sizeof(int), int.MinValue, int.MaxValue);
Console.WriteLine("{0}: bytes: {1}, range: [{2},{3}]",
typeof(long).ToString(), sizeof(long), long.MinValue, long.MaxValue);
Console.WriteLine("{0}: bytes: {1}, range: [{2},{3}]",
typeof(sbyte).ToString(), sizeof(sbyte), sbyte.MinValue, sbyte.MaxValue);
Console.WriteLine("{0}: bytes: {1}, range: [{2},{3}]",
typeof(ushort).ToString(), sizeof(ushort), ushort.MinValue, ushort.MaxValue);
Console.WriteLine("{0}: bytes: {1}, range: [{2},{3}]",
typeof(uint).ToString(), sizeof(uint), uint.MinValue, uint.MaxValue);
Console.WriteLine("{0}: bytes: {1}, range: [{2},{3}]",
typeof(ulong).ToString(), sizeof(ulong), ulong.MinValue, ulong.MaxValue);
}
}
The code above generates the following result.
