arch:: x86_64:: _mm_cvtss_si64
pub unsafe fn _mm_cvtss_si64(a: __m128) -> i64
Converts the lowest 32 bit float in the input vector to a 64 bit integer.
The result is rounded according to the current rounding mode. If the result
cannot be represented as a 64 bit integer the result will be
std::i64::MIN) or trigger an invalid operation
floating point exception if unmasked (see
This corresponds to the
CVTSS2SI instruction (with 64 bit output).
