pub unsafe fn _mm512_cvt_roundepi64_pd(
    a: __m512i,

stdarch_x86_avx512 #111137)Available on (x86 or x86-64) and target feature 
avx512dq and x86-64 only.Expand description
Convert packed signed 64-bit integers in a to packed double-precision (64-bit) floating-point elements, and store the results in dst. Rounding is done according to the ROUNDING parameter, which can be one of:
- _MM_FROUND_TO_NEAREST_INT|- _MM_FROUND_NO_EXC: round to nearest and suppress exceptions
- _MM_FROUND_TO_NEG_INF|- _MM_FROUND_NO_EXC: round down and suppress exceptions
- _MM_FROUND_TO_POS_INF|- _MM_FROUND_NO_EXC: round up and suppress exceptions
- _MM_FROUND_TO_ZERO|- _MM_FROUND_NO_EXC: truncate and suppress exceptions
- _MM_FROUND_CUR_DIRECTION: use- MXCSR.RC- see- _MM_SET_ROUNDING_MODE
