Function tract_hir::internal::tract_downcast_rs::__std::arch::x86_64::_mm_getexp_ss [−][src]
pub unsafe fn _mm_getexp_ss(a: __m128, b: __m128) -> __m128
🔬 This is a nightly-only experimental API. (
stdsimd)This is supported on x86-64 and target feature
avx512f 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.
