Syntax

C#
public static BigInteger ModularInverse( BigInteger a, BigInteger modulus )

Visual Basic (Declaration)
Public Shared Function ModularInverse ( _ a As BigInteger, _ modulus As BigInteger _ ) As BigInteger

Visual C++
public: static BigInteger ModularInverse( BigInteger a, BigInteger modulus )

F#
static member ModularInverse : a:BigInteger * modulus:BigInteger -> BigInteger

The modular inverse of a with respect to modulus.

The modular inverse exists only if a and modulus are mutually prime.

Exception	Condition
System..::.ArithmeticException	The modular inverse does not exist.
System..::.ArgumentOutOfRangeException	modulus is equal to zero.
System..::.ArithmeticException	The modular inverse does not exist.
