Instruction simd - CVTSS2SI (Convert scalar single-precision floating-point to a 32-bit integer)

instruction converts the least significant single-precision floating-point number to a 32-bit signed integer in an Intel Architecture 32-bit integer register; when the conversion is inexact, the rounded value according to the rounding mode in MXCSR is returned.The CVTTSS2SI (Convert truncate scalar single-precision floating-point to scalar 32-bit integer) instruction is similar to CVTSS2SI except if the conversion is inexact, the truncated result is returned.
