Function kvarn::prelude::compact_str::core::arch::x86_64::_mm256_maskz_getexp_pd

pub unsafe fn _mm256_maskz_getexp_pd(k: u8, a: __m256d) -> __m256d

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

Available on non-crate feature miri-test-libstd and x86-64 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 zeromask k (elements are zeroed out when the corresponding mask bit is not set). This intrinsic essentially calculates floor(log2(x)) for each element.
