Fixes up the sign of the immediate value and stores the result in the destination. Specifically, it converts a signed immediate value to a floating-point value by fixing the sign bit according to the specified immediate.

The following table covers what the source and destinations can be.

DO NOT support LOCK

This instruction is only available in 64-bit mode. It requires the AVX extension to be enabled in the processor.

To avoid unexpected behavior, ensure that the destination register is a valid XMM register. Incorrect use of the immediate field may result in a sign inversion of the resulting floating-point value.
