operator *(float, XMVECTOR) method

Multiply a floating point value by an instance of XMVECTOR, returning the result a new instance of XMVECTOR.

The operator * multiplies a floating point value against each component of an instance of XMVECTOR Data Type, returning a new XMVECTOR instance whose components contain the result.

Note  This operator is only available under C++.

 

Syntax

XMVECTOR operator *(
   float    S,
   XMVECTOR V
);

Parameters

  • S
    Floating point value used as a multiplicand for each component of V.

  • V
    XMVECTOR instance whose components are multiplicands of this multiplication operation.

Return value

XMVECTOR instance whose components are the product of the multiplication of the corresponding components of V by S.

Remarks

The following pseudocode demonstrates the operation of this operator:


   XMVECTOR V;
   Float S;
   XMVECTOR Vout;
   Vout.x = S * V1.x;
   Vout.y = S * V1.y;
   Vout.z = S * V1.z;
   Vout.w = S * V1.w;
