Function core::arch::x86::_mm_maskz_getexp_round_ss [−][src]
pub unsafe fn _mm_maskz_getexp_round_ss<const SAE: i32>(
k: __mmask8,
a: __m128,
b: __m128
) -> __m128
This is supported on x86 and target feature
avx512f only.Expand description
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 using zeromask k (the element is zeroed out when mask bit 0 is not set), 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.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
