Function surge_blitter::imports::_mm512_maskz_getexp_round_pd [−][src]
🔬 This is a nightly-only experimental API. (
stdsimd
)This is supported with 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 zeromask k (elements are zeroed out 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.
