C# Int64 and UInt64 Differences: Here, we will find out about the contrasts between C# Int64 and C# UInt64 information types.
C# Int64 and C# UInt64
In C#, Int64 known as a marked number of 8 bytes which can store the two sorts of qualities including negative and positive between the scopes of – 9223372036854775808 to +9223372036854775807.
UInt64 known as an unsigned whole number of 8 bytes which can store just positive qualities between the scopes of 0 to 18446744073709551615.
Contrasts somewhere in the range of ‘Int64’ and ‘UInt64’
| Int64 | UInt64 |
|---|---|
| Int64 stands for signed integer. | UInt64 stands for an unsigned integer. |
| It’s the capacity to store the value is -9223372036854775808 to +9223372036854775807. | Its the capacity to store the value is 0 to 18446744073709551615. |
| It can store negative and positive integers. | It can store only positive integers. |
| It occupies 8-bytes space in the memory. | It also occupies 8-bytes space in the memory. |
| Declaration syntax: Int64 variable; | Declaration syntax: UInt64 variable; |
Example:
In this example, to clarify the contrasts somewhere in the range of Int64 and UInt64 in C#, we are printing their base and greatest qualities, we are additionally announcing two exhibits – arr1 is a marked number sort and arr2 is an unsigned whole number sort. Introducing the exhibits by comparing negative and positive qualities dependent on their ability.
using System;
using System.Text;
namespace Test
{
class Program
{
static void Main(string[] args)
{
//Int64 value range
Console.WriteLine("Int64 value capacity...");
Console.WriteLine("Min: {0}, Max: {1}\n", Int64.MinValue, Int64.MaxValue);
//UInt64 value range
Console.WriteLine("UInt64 value capacity...");
Console.WriteLine("Min: {0}, Max: {1}\n", UInt64.MinValue, UInt64.MaxValue);
//Int64 array
Int64[] arr1 = {
-9223372036854775808,
0,
1287822320009,
9223372036854700000,
9223372036854775807
};
Console.WriteLine("UInt64 array elements...");
foreach (Int64 num in arr1)
{
Console.WriteLine(num);
}
Console.WriteLine();
//UInt64 array
UInt64[] arr2 = {
0,

};
Console.WriteLine("UInt64 array elements...");
foreach (UInt64 num in arr2)
{
Console.WriteLine(num);
}
//hit ENTER to exit
Console.ReadLine();
}
}
}Output:
