command mulsd destination, source
Multiplies the source operand by destination operand. Used for Multiplying Scalar Double-Precision Floating-Point Values. The mulsd command can only be used with xmm registers.
Destination = Destination * Source
Multiplies the low double-precision floating-point value in the source operand (second operand) by 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
| Parameter | Description |
|---|---|
| destination | xmm |
| source | xmm / m64 |
Examples
mulsd xmm0,xmm1
mulsd xmm3,[edx+110]
mulsd xmm15,[rdx+10]
mulsd xmm5,[00123abc]
mulsd xmm7,[UserDefinedSymbol]
