Erf ( double v0 ) : double
ErfComplement ( double v0 ) : double
FloorDivideUnchecked ( int x, int y ) : int	Calculates the quotient of two 32-bit signed integers rounded towards negative infinity. The caller must check for overflow (x = Int32.MinValue, y = -1)
FloorDivideUnchecked ( long x, long y ) : long	Calculates the quotient of two 32-bit signed integers rounded towards negative infinity. The caller must check for overflow (x = Int64.MinValue, y = -1)
FloorRemainder ( int x, int y ) : int	Calculates the remainder of floor division of two 32-bit signed integers.
FloorRemainder ( long x, long y ) : long	Calculates the remainder of floor division of two 32-bit signed integers.
Gamma ( double v0 ) : double
GetBitCount ( this self ) : int
GetByteCount ( this self ) : int
GetRandBits ( this generator, int bits ) : BigInteger
GetRandBits ( this generator, int bits ) : System.Numerics.BigInteger
GetWordCount ( this self ) : int
Hypot ( double x, double y ) : double
Imaginary ( this self ) : double
IsNegative ( this self ) : bool
IsNegativeZero ( double self ) : bool
IsPositive ( this self ) : bool
IsZero ( this self ) : bool
Log ( this self ) : double

MakeImaginary ( double imag ) : Complex64
MakeImaginary ( double imag ) : System.Numerics.Complex
MakeReal ( double real ) : Complex64
MakeReal ( double real ) : System.Numerics.Complex
ModPow ( this self, System.Numerics.BigInteger power, System.Numerics.BigInteger mod ) : System.Numerics.BigInteger
ModPow ( this self, int power, System.Numerics.BigInteger mod ) : System.Numerics.BigInteger

Pow ( this self, System.Numerics.Complex power ) : System.Numerics.Complex
Power ( this self, int exp ) : System.Numerics.BigInteger
Random ( this generator, BigInteger limit ) : BigInteger
Random ( this generator, System.Numerics.BigInteger limit ) : System.Numerics.BigInteger
RoundAwayFromZero ( double value ) : double	Behaves like Math.Round(value, MidpointRounding.AwayFromZero) Needed because CoreCLR doesn't support this particular overload of Math.Round
RoundAwayFromZero ( double value, int precision ) : double	Behaves like Math.Round(value, precision, MidpointRounding.AwayFromZero) However, it works correctly on negative precisions and cases where precision is outside of the [-15, 15] range. (This function is also needed because CoreCLR lacks this overload.)
ToFloat64 ( this self ) : double
ToString ( this self, int radix ) : string
TryToFloat64 ( this self, double &result ) : bool
