Function npyv_maxp_f32

numpy/core/src/common/simd/sse/math.h:46–51

Maximum, supports IEEE floating-point arithmetic (IEC 60559), - If one of the two vectors contains NaN, the equivalent element of the other vector is set - Only if both corresponded elements are NaN, NaN is set.

// - If one of the two vectors contains NaN, the equivalent element of the other vector is set
// - Only if both corresponded elements are NaN, NaN is set.
