pub unsafe fn _mm_mask_getexp_ps(src: __m128, k: __mmask8, a: __m128) -> __m128
🔬 This is a nightly-only experimental API. (stdsimd #48556)
Available on x86 and target feature avx512f,avx512vl only.
Expand description

Convert the exponent of each packed single-precision (32-bit) floating-point element in a to a single-precision (32-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.
