Expand description

Convert packed single-precision (32-bit) floating-point elements in a to packed half-precision (16-bit) floating-point elements, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
Rounding is done according to the rounding[3:0] parameter, which can be one of:

- `_MM_FROUND_TO_NEAREST_INT` // round to nearest
- `_MM_FROUND_TO_NEG_INF` // round down
- `_MM_FROUND_TO_POS_INF` // round up
- `_MM_FROUND_TO_ZERO` // truncate
- `_MM_FROUND_CUR_DIRECTION` // use MXCSR.RC; see `_MM_SET_ROUNDING_MODE`
- `_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` | `_MM_FROUND_NO_EXC` // use MXCSR.RC and suppress exceptions; see `_MM_SET_ROUNDING_MODE`
