arch::[−][src] x86:: _mm512_mask_getexp_round_pd
pub unsafe fn _mm512_mask_getexp_round_pd<const SAE: i32>(
) -> __m512d
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.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
