Calculates tangent value. Vector variant of tan(x) function for a float64 argument. This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).
Without Mask extern _m512d __cdecl _mm512_tan_pd(_m512d v2); |
With Mask extern _m512d __cdecl _mm512_mask_tan_pd(_m512d v1_old, __mmask8 k1, _m512d v2); |
v2 |
vector with float64 values |
v1_old |
Source vector that retains old values of the destination vector; the resulting vector gets corresponding elements from v1_old for zero mask bits |
k1 |
Writemask; only those elements of the source vectors with corresponding bit set to '1' in the k1 mask are computed and stored in the result; elements in the result vector corresponding to zero bit in k1 are copied from corresponding elements of vector v1_old |
Calculates the tangent (in radians) of vector v2 elements. In effect, the arc tangent of each resulting element value is the value of the corresponding v2 vector element.
The masked variant has two additional arguments: v1_old and k1. Those elements of v2 with the corresponding bit clear in vector mask k1 are not used in the computation. Instead, the corresponding element from v1_old is copied to the resulting vector.
Returns the result of the operation.
