VGETEXPPD

Extracts the exponent of the packed double-precision floating-point values from the source operands and stores the result as signed integers in the destination operand.

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

DO NOT support LOCK

This instruction SHALL only be executed in 64-bit mode or compatibility mode. It is part of the AVX-512 extension set; therefore, it REQUIRES a processor that supports AVX-512.

The result is stored as a signed 32-bit integer for each 64-bit floating-point element. Users MUST ensure that the destination register is of sufficient size to hold the resulting packed 32-bit integers to avoid data truncation or unexpected behavior. When using masking (k-registers), elements that are masked out SHALL retain their original values in the destination register.
