Function core::arch::x86_64::_mm256_maskz_getexp_ps

pub unsafe fn _mm256_maskz_getexp_ps(k: __mmask8, a: __m256) -> __m256

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

This is supported on x86-64 and target feature avx512f,avx512vl only.

Convert the exponent of each packed single-precision (32-bit) floating-point element in a to a single-precision (32-bit) floating-point number representing the integer exponent, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set). This intrinsic essentially calculates floor(log2(x)) for each element.
