Difference between Int64 and UInt64 in C#
Int64: This Struct is used to represents 64-bit signed integer. The Int64 can store both types of values including negative and positive between the ranges of -9,223,372,036,854,775,808 to +9, 223,372,036,854,775,807
Example :
C#
// C# program to show the // difference between Int64 // and UInt64 using System; using System.Text; public class GFG { // Main Method static void Main( string [] args) { // printing minimum & maximum values Console.WriteLine( "Minimum value of Int64: " + Int64.MinValue); Console.WriteLine( "Maximum value of Int64: " + Int64.MaxValue); Console.WriteLine(); // Int64 array Int64[] arr1 = {-3, 0, 1, 3, 7}; foreach (Int64 i in arr1) { Console.WriteLine(i); } } } |
Output:
Minimum value of Int64: -9223372036854775808 Maximum value of Int64: 9223372036854775807 -3 0 1 3 7
UInt64: This Struct is used to represents 64-bit unsigned integer. The UInt64 can store only positive value only which ranges from 0 to 18,446,744,073,709,551,615.
Example :
C#
// C# program to show the // difference between Int64 // and UInt64 using System; using System.Text; public class GFG{ // Main Method static void Main( string [] args) { //printing minimum & maximum values Console.WriteLine( "Minimum value of UInt64: " + UInt64.MinValue); Console.WriteLine( "Maximum value of UInt64: " + UInt64.MaxValue); Console.WriteLine(); //Int64 array UInt64[] arr1 = { 13, 0, 1, 3, 7}; foreach (UInt64 i in arr1) { Console.WriteLine(i); } } } |
Output:
Minimum value of UInt64: 0 Maximum value of UInt64: 18446744073709551615 13 0 1 3 7
