Function core::arch::x86_64::_mm_maskz_getexp_pd [−][src]
pub unsafe fn _mm_maskz_getexp_pd(k: __mmask8, a: __m128d) -> __m128d
This is supported on x86-64 and target feature
avx512f,avx512vl only.Expand description
Convert the exponent of each packed double-precision (64-bit) floating-point element in a to a double-precision (64-bit) floating-point number representing the integer exponent, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set). This intrinsic essentially calculates floor(log2(x)) for each element.
