BigInteger.CompareTo Method (Int64)

Compares this instance to a signed 64-bit integer and returns an integer that indicates whether the value of this instance is less than, equal to, or greater than the value of the signed 64-bit integer.

Namespace:  System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)

public int CompareTo(
	long other
)

Parameters

other
Type: System.Int64

The signed 64-bit integer to compare.

Return Value

Type: System.Int32
A signed integer value that indicates the relationship of this instance to other, as shown in the following table.

Return value

Description

Less than zero

The current instance is less than other.

Zero

The current instance equals other.

Greater than zero

The current instance is greater than other.

If other is a Byte, Int16, Int32, SByte, UInt16, or UInt32 value, it is implicitly converted to an Int64 value when the CompareTo(Int64) method is called.

The following example illustrates the result of calling the CompareTo(Int64) method with integral values.

BigInteger bigIntValue = BigInteger.Parse("3221123045552");

byte byteValue = 16;
sbyte sbyteValue = -16;
short shortValue = 1233;      
ushort ushortValue = 1233;
int intValue = -12233;
uint uintValue = 12233;
long longValue = 12382222;
ulong ulongValue = 1238222;

Console.WriteLine("Comparing {0} with {1}: {2}", 
                  bigIntValue, byteValue, 
                  bigIntValue.CompareTo(byteValue));
Console.WriteLine("Comparing {0} with {1}: {2}", 
                  bigIntValue, sbyteValue, 
                  bigIntValue.CompareTo(sbyteValue)); 
Console.WriteLine("Comparing {0} with {1}: {2}", 
                  bigIntValue, shortValue, 
                  bigIntValue.CompareTo(shortValue));
Console.WriteLine("Comparing {0} with {1}: {2}", 
                  bigIntValue, ushortValue, 
                  bigIntValue.CompareTo(ushortValue)); 
Console.WriteLine("Comparing {0} with {1}: {2}", 
                  bigIntValue, intValue, 
                  bigIntValue.CompareTo(intValue));
Console.WriteLine("Comparing {0} with {1}: {2}", 
                  bigIntValue, uintValue, 
                  bigIntValue.CompareTo(uintValue)); 
Console.WriteLine("Comparing {0} with {1}: {2}", 
                  bigIntValue, longValue, 
                  bigIntValue.CompareTo(longValue));
Console.WriteLine("Comparing {0} with {1}: {2}", 
                  bigIntValue, ulongValue, 
                  bigIntValue.CompareTo(ulongValue));
// The example displays the following output: 
//       Comparing 3221123045552 with 16: 1 
//       Comparing 3221123045552 with -16: 1
