pub unsafe fn _mm_cvttss_si64(a: __m128) -> i64
Converts the lowest 32 bit float in the input vector to a 64 bit integer with truncation.
The result is rounded always using truncation (round towards zero). If the
result cannot be represented as a 64 bit integer the result will be
std::i64::MIN) or an invalid operation floating
point exception if unmasked (see
This corresponds to the
CVTTSS2SI instruction (with 64 bit output).
