_mm_getexp_round_ss in core::arch::x86_64 - Rust
Description: 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.

# Function core::arch::x86_64::_mm_getexp_round_ss
[−][src]

    pub unsafe fn _mm_getexp_round_ss(a: __m128, b: __m128, sae: i32) -> __m128

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f` only.
