Functions

func ExtractBitsFromU32

func ExtractBitsFromU32(num uint32, loInclude, hiInclude int) uint32

ExtractBitsFromU32 will get the bits from loInclude to hiInclude.

func ExtractBitsFromU64

func ExtractBitsFromU64(num uint64, loInclude, hiInclude int) uint64

ExtractBitsFromU64 will get the bits from loInclude to hiInclude.

func SignExt

func SignExt(in uint64, signBit int) (out uint64)

SignExt updates all the bits beyond the signBit to be the same as the sign bit.
