Function core::arch::x86::_mm256_mask_getexp_pd

pub unsafe fn _mm256_mask_getexp_pd(
    src: __m256d, 
    k: __mmask8, 
    a: __m256d
) -> __m256d

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on x86 and target feature avx512f,avx512vl only.

Convert the exponent of each packed double-precision (64-bit) floating-point element in a to a double-precision (64-bit) floating-point number representing the integer exponent, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set). This intrinsic essentially calculates floor(log2(x)) for each element.
