Assembler:Commands:CVTSI2SS
command cvtsi2ss destination, source
Converts doubleword integer to single precision floating point value. Used for Converting Doubleword Integer To Scalar-Single-Precision Floating-Point Values. The cvtsi2ss command must be used with xmm registers.
Converts a signed doubleword integer in the source operand (second operand) to a single-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 doubleword of the destination operand, and the upper three doublewords are left unchanged. When a conversion is inexact, the value returned is rounded according to the rounding control bits in the MXCSR register.
