# [−][src]Function core::arch::x86_64::_mm256_cvtps_ph

    pub unsafe fn _mm256_cvtps_ph(a: __m256, imm_rounding: i32) -> __m128i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `f16c` only.

Converts the 8 x 32-bit float values in the 256-bit vector `a` into 8 x 16-bit half-precision float values stored in a 128-bit wide vector.

Rounding is done according to the `imm_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`.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
