Function serde::lib::core::arch::x86_64::_mm_maskz_getexp_ph

pub unsafe fn _mm_maskz_getexp_ph(k: u8, a: __m128h) -> __m128h

🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16)

Available on x86-64 only.

Convert the exponent of each packed half-precision (16-bit) floating-point element in a to a half-precision (16-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.
