BigInteger.LessThan Operator (Int64, BigInteger)

Returns a value that indicates whether a 64-bit signed integer is less than a BigInteger value.

Namespace:  System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)
public static bool operator <(
	long left,
	BigInteger right
)

Parameters

left
Type: System.Int64

The first value to compare.

right
Type: System.Numerics.BigInteger

The second value to compare.

Return Value

Type: System.Boolean
true if left is less than right; otherwise, false.

The LessThan method defines the operation of the less than operator for BigInteger values. It enables code such as the following:

BigInteger number = BigInteger.Parse("9801324316220166912");
if (Int64.MaxValue < number)
{
   // Do something.
}
else
{
   // Do something else.
}      

Languages that do not support custom operators can call the BigInteger.CompareTo(Int64) method instead. Some languages can also call the LessThan(Int64, BigInteger) method directly, as the following example shows.

Dim number As BigInteger = BigInteger.Parse("9801324316220166912")
If BigInteger.op_LessThan(Int64.MaxValue, number) Then 
   ' Do something. 
Else 
   ' Do something else. 
End If

If left is a Byte, Int16, Int32, SByte, UInt16, or UInt32 value, it is implicitly converted to an Int64 value when the operation is performed.
