BigInteger.Add(BigInteger, BigInteger) Method

Definition

Adds two BigInteger values and returns the result.

C#
public static System.Numerics.BigInteger Add(System.Numerics.BigInteger left, System.Numerics.BigInteger right);

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.

C#
// 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);
