command subsd destination, source
Subtracts the source from the destination. Used for Subtracting Scalar Double-Precision Floating-Point Values. The subsd command can only be used with xmm registers.
Destination = Destination - Source
Subtracts the low double-precision floating-point value in the source operand (second operand) from the low double-precision floating-point value in the destination operand (first operand), and stores the double-precision floating-point result in the destination operand. The source operand can be an XMM register or a 64-bit memory location. The destination operand is an XMM register. The high quadword of the destination operand remains unchanged.
Command Parameters[edit]
| Parameter | Description |
|---|---|
| destination | xmm |
| source | xmm / m64 |
Examples[edit]
subsd xmm0,xmm1
subsd xmm3,[edx+110]
subsd xmm15,[rdx+10]
subsd xmm5,[00123abc]
subsd xmm7,[UserDefinedSymbol]
