CVTSD2SI
Usage: CVTSD2SI dest,src Modifies flags: None
Converts a double-precision floating-point value in the 'src' to a signed doubleword integer in the 'dest' operand.
Scalar Double-Precision FP to Signed INT32 Conversion
CVTSD2SI reg32,xmm/mem64 ; F2 0F 2D /r [WILLAMETTE,SSE2]
CVTSD2SI converts a double-precision FP value from the source operand to a signed doubleword in the destination operand contained in the low quadword of the register.
The destination operand is a general purpose register. The source can be either an XMM register or a 64-bit memory location. If the source is a register, the input value is in the low quadword. For more details of this instruction, see the Intel Processor manuals.
Example:
