A.5.46 CVTSD2SS: Scalar Double-Precision FP to Scalar Single-Precision FP
Conversion
CVTSD2SS xmm1,xmm2/mem64 ; F2 0F 5A /r [KATMAI,SSE]
CVTSD2SS converts a double-precision FP value from the source operand
to a single-precision FP value in the low doubleword of the destination
operand. The upper 3 doublewords are left unchanged.
The destination operand is an XMM 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.
