Name Description
MultiplyAddEstimate(Vector128<Double>, Vector128<Double>, Vector128<Double>)

Computes an estimate of (left * right) + addend.
MultiplyAddEstimate(Vector128<Single>, Vector128<Single>, Vector128<Single>)

Computes an estimate of (left * right) + addend.

MultiplyAddEstimate(Vector128<Double>, Vector128<Double>, Vector128<Double>)

Source:
Vector128.cs

Computes an estimate of (left * right) + addend.

public:
 static System::Runtime::Intrinsics::Vector128<double> MultiplyAddEstimate(System::Runtime::Intrinsics::Vector128<double> left, System::Runtime::Intrinsics::Vector128<double> right, System::Runtime::Intrinsics::Vector128<double> addend);
public static System.Runtime.Intrinsics.Vector128<double> MultiplyAddEstimate(System.Runtime.Intrinsics.Vector128<double> left, System.Runtime.Intrinsics.Vector128<double> right, System.Runtime.Intrinsics.Vector128<double> addend);
static member MultiplyAddEstimate : System.Runtime.Intrinsics.Vector128<double> * System.Runtime.Intrinsics.Vector128<double> * System.Runtime.Intrinsics.Vector128<double> -> System.Runtime.Intrinsics.Vector128<double>
Public Function MultiplyAddEstimate (left As Vector128(Of Double), right As Vector128(Of Double), addend As Vector128(Of Double)) As Vector128(Of Double)

Parameters

left
Vector128<Double>

The vector to be multiplied with right.

right
Vector128<Double>

The vector to be multiplied with left.

addend
Vector128<Double>

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

Returns

Vector128<Double>

An estimate of (left * right) + addend.

Remarks

On hardware that natively supports FusedMultiplyAdd(Vector128<Double>, Vector128<Double>, Vector128<Double>), this method might return a result that was rounded as one ternary operation.

On hardware without specialized support, this method might just return (left * right) + addend.

Public Function MultiplyAddEstimate (left As Vector128(Of Single), right As Vector128(Of Single), addend As Vector128(Of Single)) As Vector128(Of Single)

Parameters

left
Vector128<Single>

The vector to be multiplied with right.
