command cvtsi2sd destination, source

Converts doubleword integer to double precision floating point value. Used for Converting Doubleword Integer To Scalar-Double-Precision Floating-Point Values. The cvtsi2sd command must be used with xmm registers.


Converts a signed doubleword integer in the source operand (second operand) to a double-precision floating-point value in the destination operand (first operand). The source operand can be a general-purpose register or a 32-bit memory location. The destination operand is an XMM register. The result is stored in the low quadword of the destination operand, and the high quadword left unchanged.
