Converts four packed single-precision floating-point values in the source operand (second operand) to four packed signed doubleword integers in the destination operand (first operand).

The source operand can be an XMM register or a 128-bit memory location. The destination operand is an XMM register.

When a conversion is inexact, the value returned is rounded according to the rounding control bits in the MXCSR register. If a converted result is larger than the maximum signed doubleword integer, the floating-point invalid exception is raised, and if this exception is masked, the indefinite integer value (80000000H) is returned.

Destination[0..31] = ConvertFloatToInteger(Source[0..31]);
Destination[32..63] = ConvertFloatToInteger(Source[32..63]);
Destination[64..95] = ConvertFloatToInteger(Source[64..95]);
Destination[96..127] = ConvertFloatToInteger(Source[96..127]);
