Function serde::lib::core::arch::x86_64::_mm_getexp_round_ss

pub unsafe fn _mm_getexp_round_ss<const SAE: i32>(
    a: __m128,
    b: __m128,
) -> __m128

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 only.

Convert the exponent of the lower single-precision (32-bit) floating-point element in b to a single-precision (32-bit) floating-point number representing the integer exponent, store the result in the lower element of dst, and copy the upper 3 packed elements from a to the upper elements of dst. This intrinsic essentially calculates floor(log2(x)) for the lower element.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
