VFEXTRACT

Operation

Copies one indexed floating-point vector lane to a floating-point scalar register.

Assembler Syntax

VFEXTRACT interprets the scalar index as unsigned and selects that lane from Vn. The H, S, and D forms copy the selected floating-point value to Fn and leave FFLAGS unchanged.

An index at or above the selected vector element count raises VECTOR_LANE_INDEX_OUT_OF_RANGE. The faulting instruction commits no scalar result.
