Definition

Namespace:

System.Numerics

Assembly:

System.Numerics.Vectors.dll

Overloads

FusedMultiplyAdd(Vector<Double>, Vector<Double>, Vector<Double>)	Computes (left * right) + addend, rounded as one ternary operation.
FusedMultiplyAdd(Vector<Single>, Vector<Single>, Vector<Single>)	Computes (left * right) + addend, rounded as one ternary operation.

FusedMultiplyAdd(Vector<Double>, Vector<Double>, Vector<Double>)

Computes (left * right) + addend, rounded as one ternary operation.

public:
 static System::Numerics::Vector<double> FusedMultiplyAdd(System::Numerics::Vector<double> left, System::Numerics::Vector<double> right, System::Numerics::Vector<double> addend);

public static System.Numerics.Vector<double> FusedMultiplyAdd (System.Numerics.Vector<double> left, System.Numerics.Vector<double> right, System.Numerics.Vector<double> addend);

static member FusedMultiplyAdd : System.Numerics.Vector<double> * System.Numerics.Vector<double> * System.Numerics.Vector<double> -> System.Numerics.Vector<double>

Public Function FusedMultiplyAdd (left As Vector(Of Double), right As Vector(Of Double), addend As Vector(Of Double)) As Vector(Of Double)

Parameters

left

Vector<Double>

The vector to be multiplied with right.

right

Vector<Double>

The vector to be multiplied with left.

addend

Vector<Double>

The vector to be added to the result of left multiplied by right.

Returns

Vector<Double>

(left * right) + addend, rounded as one ternary operation.

Remarks

This computes (left * right) as if to infinite precision, adds addend to that result as if to infinite precision, and finally rounds to the nearest representable value.

This differs from the non-fused sequence which would compute (left * right) as if to infinite precision, round the result to the nearest representable value, add addend to the rounded result as if to infinite precision, and finally round to the nearest representable value.

FusedMultiplyAdd(Vector<Single>, Vector<Single>, Vector<Single>)

Computes (left * right) + addend, rounded as one ternary operation.

public:
 static System::Numerics::Vector<float> FusedMultiplyAdd(System::Numerics::Vector<float> left, System::Numerics::Vector<float> right, System::Numerics::Vector<float> addend);

public static System.Numerics.Vector<float> FusedMultiplyAdd (System.Numerics.Vector<float> left, System.Numerics.Vector<float> right, System.Numerics.Vector<float> addend);

static member FusedMultiplyAdd : System.Numerics.Vector<single> * System.Numerics.Vector<single> * System.Numerics.Vector<single> -> System.Numerics.Vector<single>

Public Function FusedMultiplyAdd (left As Vector(Of Single), right As Vector(Of Single), addend As Vector(Of Single)) As Vector(Of Single)

Parameters

left

Vector<Single>

The vector to be multiplied with right.

right

Vector<Single>

The vector to be multiplied with left.

addend

Vector<Single>

The vector to be added to the result of left multiplied by right.

Returns

Vector<Single>

(left * right) + addend, rounded as one ternary operation.

Remarks

This computes (left * right) as if to infinite precision, adds addend to that result as if to infinite precision, and finally rounds to the nearest representable value.

This differs from the non-fused sequence which would compute (left * right) as if to infinite precision, round the result to the nearest representable value, add addend to the rounded result as if to infinite precision, and finally round to the nearest representable value.
