🔬This is a nightly-only experimental API. (

#111137)Available on (x86 or x86-64) and target feature
avx512dq
and x86-64 only.Expand description
Convert packed double-precision (64-bit) floating-point elements in a to packed signed 64-bit integers, and store the results in dst using writemask k (elements are copied from src if the corresponding bit is not set). 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
