Subtracts one BigInteger value from another and returns the result.
public:
static System::Numerics::BigInteger Subtract(System::Numerics::BigInteger left, System::Numerics::BigInteger right);
public static System.Numerics.BigInteger Subtract(System.Numerics.BigInteger left, System.Numerics.BigInteger right);
static member Subtract : System.Numerics.BigInteger * System.Numerics.BigInteger -> System.Numerics.BigInteger
Public Shared Function Subtract (left As BigInteger, right As BigInteger) As BigInteger
The value to subtract from (the minuend).
The value to subtract (the subtrahend).
The result of subtracting right
from left
.
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.
// 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);
let number = BigInteger.Subtract(Int64.MinValue, Int64.MaxValue);
' The statement
' Dim number As BigInteger = Int64.MinValue - Int64.MaxValue
' produces compiler error BC30439: Constant expression not representable in type 'Long'.
' The alternative:
Dim number As BigInteger = BigInteger.Subtract(Int64.MinValue, Int64.MaxValue)
