Adds two BigInteger values and returns the result.
public:
static System::Numerics::BigInteger Add(System::Numerics::BigInteger left, System::Numerics::BigInteger right);
public static System.Numerics.BigInteger Add (System.Numerics.BigInteger left, System.Numerics.BigInteger right);
static member Add : System.Numerics.BigInteger * System.Numerics.BigInteger -> System.Numerics.BigInteger
Public Shared Function Add (left As BigInteger, right As BigInteger) As BigInteger
Parameters
- left
- BigInteger
The first value to add.
- right
- BigInteger
The second value to add.
Returns
The sum of left
and right
.
Remarks
Languages that do not support operator overloading or custom operators can use the Add method to perform addition using BigInteger values.
The Add method is a useful substitute for the addition operator when instantiating a BigInteger variable by assigning it a sum that results from addition, as shown in the following example.
// The statement:
// BigInteger number = Int64.MaxValue + Int32.MaxValue;
// produces compiler error CS0220: The operation overflows at compile time in checked mode.
// The alternative:
BigInteger number = BigInteger.Add(Int64.MaxValue, Int32.MaxValue);
let number = BigInteger.Add(Int64.MaxValue, Int32.MaxValue);
' The statement
' Dim number As BigInteger = Int64.MaxValue + Int32.MaxValue
' produces compiler error BC30439: Constant expression not representable in type 'Long'.
' The alternative:
Dim number As BigInteger = BigInteger.Add(Int64.MaxValue, Int32.MaxValue)
