Expand description

Convert packed half-precision (16-bit) floating-point elements in a to packed 32-bit integers, 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`
