Returns the cross product of p0.xyz
and p1.xyz
. The
w
component of the float4 result (or double
if the cl_khr_fp16
extension is enabled) will be 0.0.
Built-in geometric functions operate component-wise. The description
is per-component. floatn
is
float, float2, float3, or float4 and
doublen
is double, double2,
double3, or double4. The built-in geometric functions are
implemented using the round to nearest even rounding mode.
The geometric functions can be implemented using contractions such as mad or fma.
An application that wants to use half
and halfn
types will need to include the #pragma OPENCL EXTENSION
cl_khr_fp16 : enable
directive.
