CVTPI2PD

Converts a signed integer value to a double-precision floating-point value.

The following table covers the supported source and destinations:

DO NOT support LOCK

This instruction is available in 64-bit mode and compatibility mode. It requires the SSE2 instruction set.

The source operand must be a signed 32-bit integer (i32). The operation performs a conversion from a signed integer to a double-precision floating-point format. If the result cannot be represented exactly in the destination format, the result is rounded according to the rounding control word in the MXCSR register. A precision exception (#P) may be signaled if the result is rounded.
