pub unsafe fn _mm512_getexp_round_pd<const SAE: i32>(a: __m512d) -> __m512d🔬This is a nightly-only experimental API. (
stdarch_x86_avx512)Available on 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.
