Function core::arch::x86_64::_mm512_maskz_getexp_round_pd

pub unsafe fn _mm512_maskz_getexp_round_pd(
    k: __mmask8,
    a: __m512d,
    const SAE: i32
) -> __m512d

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

Available on x86-64 and target feature avx512f 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.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
