command subss destination, source

Subtracts the source from the destination. Used for Subtracting Scalar Single-Precision Floating-Point Values. The subss command can only be used with xmm registers.


Destination = Destination - Source


Subtracts the low single-precision floating-point value in the source operand (second operand) from the low single-precision floating-point value in the destination operand (first operand), and stores the single-precision floating-point result in the destination operand. The source operand can be an XMM register or a 32-bit memory location. The destination operand is an XMM register. The three high-order doublewords of the destination operand remain unchanged.
