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.
Command Parameters[edit]
| Parameter | Description |
|---|---|
| destination | xmm |
| source | xmm / m32 |
Examples[edit]
subss xmm0,xmm1
subss xmm3,[edx+110]
subss xmm15,[rdx+10]
subss xmm5,[00123abc]
subss xmm7,[UserDefinedSymbol]
