_mm_getexp_round_sh in core::arch::x86 - Rust
Description: Convert the exponent of the lower half-precision (16-bit) floating-point element in b to a half-precision (16-bit) floating-point number representing the integer exponent, store the result in the lower element of dst, and copy the upper 7 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
