command cvtdq2ps destination, source
Converts doubleword integer to single precision floating point value. Used for Converting Packed-Doubleword To Packed-Single-Precision Floating-Point Values. The cvtdq2ps command must be used with xmm registers.
Converts four packed signed doubleword integers in the source operand (second operand) to four packed single-precision floating-point values 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, rounding is performed according to the rounding control bits in the MXCSR register.
