pub fn _mm_cvt_roundsh_ss<const SAE: i32>(a: __m128, b: __m128h) -> __m128🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16)Expand description
Convert the lower half-precision (16-bit) floating-point element in b to a single-precision (32-bit) floating-point element, store the result in the lower element of dst, and copy the upper 3 packed elements from a to the upper elements of dst.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
