A.5.210 PF2ID: Packed Single-Precision FP to Integer Convert
PF2ID mm1,mm2/m64 ; 0F 0F /r 1D [PENT,3DNOW]
PF2ID converts two single-precision FP values in the source operand
to signed 32-bit integers, using truncation, and stores them in the
destination operand. Source values that are outside the range supported
by the destination are saturated to the largest absolute value of the
same sign.
