Public Methods

Method Description
Abs ( BigInteger b ) : BigInteger

Gets the absolute value of a BigInteger object.
Add ( BigInteger left, BigInteger right ) : BigInteger

Adds two BigInteger values and returns the result.
BigInteger ( int value ) : System

Initializes a new instance of the BigInteger structure using a 32-bit signed integer value.
BigInteger ( long value ) : System

Initializes a new instance of the BigInteger structure using a 64-bit signed integer value.
Compare ( BigInteger a, BigInteger b ) : int

Returns -1 if a < b, 0 if they are the same, or 1 if a > b.
Equals ( object obj ) : bool

Returns a value that indicates whether the current instance and a specified BigInteger object have the same value.
FromDouble ( double value ) : BigInteger

Returns a new instance BigInteger structure from a 64-bit double precision floating point value.
GetHashCode ( ) : int

Returns the hash code for the current BigInteger object.
InPlaceDecrement ( ) : void

Decrements the current value of the BigInteger object.
LeftShift ( BigInteger value, int shift ) : BigInteger

Shifts a BigInteger value a specified number of bits to the left.
Log ( BigInteger value, double baseValue ) : double

Returns the logarithm of a specified number in a specified base.

Shifts a BigInteger value a specified number of bits to the right.

Note: unlike System.Numerics.BigInteger, negative numbers are treated identically to positive numbers.

SetupQuorum ( BigInteger &dividend, BigInteger &divisor ) : void

Modifies the given values so they are suitable for passing to Quorem.
SetupQuorum ( BigInteger &dividend, BigInteger &divisor, BigInteger &other ) : void

Modifies the given values so they are suitable for passing to Quorem.
Subtract ( BigInteger left, BigInteger right ) : BigInteger

Subtracts one BigInteger value from another and returns the result.
ToDouble ( ) : double

Returns a double that corresponds to the BigInteger value.
ToString ( ) : string

Converts the numeric value of the current BigInteger object to its equivalent string representation.
