# Function core::arch::x86_64::_mm512_maskz_getexp_round_ps
[−][src]

    pub unsafe fn _mm512_maskz_getexp_round_ps<const SAE: i32>(
        k: __mmask16,
        a: __m512
    ) -> __m512

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f` 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 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.
