BigInteger.Subtract(BigInteger, BigInteger) Method

Definition

Subtracts one BigInteger value from another and returns the result.

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

Parameters

left
BigInteger

The value to subtract from (the minuend).

right
BigInteger

The value to subtract (the subtrahend).

Returns

The result of subtracting right from left.

Remarks

Languages that do not support custom operators can use the Subtract method to perform subtraction using BigInteger values.

The Subtract method is a useful substitute for the subtraction operator when instantiating a BigInteger variable by assigning it the difference that results from subtraction, as shown in the following example.

C#
// The statement
//    BigInteger number = Int64.MinValue - Int64.MaxValue;
// produces compiler error CS0220: The operation overflows at compile time in checked mode.
// The alternative:
BigInteger number = BigInteger.Subtract(Int64.MinValue, Int64.MaxValue);
