Expand description

Converts the lowest 32 bit float in the input vector to a 32 bit integer with truncation.

The result is rounded always using truncation (round towards zero). If the result cannot be represented as a 32 bit integer the result will be `0x8000_0000` (`i32::MIN`).

This corresponds to the `CVTTSS2SI` instruction (with 32 bit output).
