CVTTPD2DQ
Usage: CVTTPD2DQ dest,src Modifies flags: None
Converts two packed double-precision floating-point values in the 'src' operand to two packed signed doubleword integers in the 'dest' operand.
Packed Double-Precision FP to Packed Signed INT32 Conversion with Truncation
CVTTPD2DQ xmm1,xmm2/mem128 ; 66 0F E6 /r [WILLAMETTE,SSE2]
CVTTPD2DQ converts two packed double-precision FP values in the source operand to two packed double-precision FP values in the destination operand. If the result is inexact, it is truncated (rounded toward zero). The high quadword is set to all 0s.
The destination operand is an XMM register. The source can be either an XMM register or a 128-bit memory location. For more details of this see the Intel Processor manuals.
Example:
