Function core::arch::x86_64::_mm512_mask_getexp_pd [−][src]
pub unsafe fn _mm512_mask_getexp_pd(
src: __m512d,
k: __mmask8,
a: __m512d
) -> __m512d
This is supported on x86-64 and target feature
avx512f
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 writemask k (elements are copied from src when the corresponding mask bit is not set). This intrinsic essentially calculates floor(log2(x)) for each element.
