XMVector4NearEqual method

Tests whether one 4D vector is near another 4D vector.

Syntax


bool XMVector4NearEqual(
  [in]  XMVECTOR V1,
  [in]  XMVECTOR V2,
  [in]  XMVECTOR Epsilon
);

Parameters

V1 [in]

4D vector.

V2 [in]

4D vector.

Epsilon [in]

Tolerance value used for judging equality.

Return value

Returns true if V1 is near V2 and false otherwise.

Remarks

The following pseudocode demonstrates the operation of the function:


return ( ( abs( V1.x - V2.x ) <= Epsilon ) && 
         ( abs( V1.y - V2.y ) <= Epsilon ) && 
         ( abs( V1.z - V2.z ) <= Epsilon ) &&
         ( abs( V1.w - V2.w ) <= Epsilon ));

Platform Requirements

Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
