_mm_atan_ps

Calculates arc tangent value. Vector variant of atan(x) function for a 128-bit vector argument of four float32 values.

Syntax

extern __m128 __cdecl _mm_atan_ps(__m128 v1);

Arguments

v1

128-bit vector with float32 values

Description

Calculates the arc tangent of vector v1 elements. In effect, the tangent of each resulting element value is the value of the corresponding v1 vector element.

Returns

128-bit vector with result of the operation.
