Function core::arch::x86_64::_mm_getexp_ph
source · pub unsafe fn _mm_getexp_ph(a: __m128h) -> __m128h🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16 #127213)Available on (x86 or x86-64) and target feature
avx512fp16,avx512vl and x86-64 only.Expand description
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.
This intrinsic essentially calculates floor(log2(x)) for each element.
