[−][src]

    pub unsafe fn _mm256_mask_getexp_ps(
        src: __m256,
        k: __mmask8,
        a: __m256
    ) -> __m256

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512f,avx512vl` only.
Expand description

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 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.
