🔬This is a nightly-only experimental API. (stdsimd #48556)
Available on (x86 or x86-64) and target feature avx512f and x86-64 only.
Expand description

Compare packed double-precision (64-bit) floating-point elements in a and b based on the comparison operand specified by imm8, and store the results in mask vector k.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
