Function core::arch::x86_64::_mm512_getexp_round_pd
source · pub unsafe fn _mm512_getexp_round_pd(a: __m512d, const SAE: i32) -> __m512d🔬This is a nightly-only experimental API. (
stdsimd #48556)Available on (x86 or x86-64) and target feature
avx512f and x86-64 only.Expand description
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. This intrinsic essentially calculates floor(log2(x)) for each element.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
