only.Expand description
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
0x8000_0000_0000_0000
(i64::MIN
) or trigger an invalid operation
floating point exception if unmasked (see
_mm_setcsr
).
This corresponds to the CVTSS2SI
instruction (with 64 bit output).
