Haskus.Binary.Bits.Shift

Description

Bit shifts

Synopsis

Documentation

class ShiftableBits a where Source #

Bit shifts

Checked means that there is an additional test to ensure that the shift offset is valid (less than the bit count). If you are sure that the offset is valid, use the "unchecked" version which should be faster.

To shift signed numbers, see SignedShiftableBits class methods.

class SignedShiftableBits a where Source #

Signed bit shifts

Signed means that the sign bit (the higher order bit): - propagates to the right during right shifts and - keeps its value during left shifts (except when all other bits are 0)

Checked means that there is an additional test to ensure that the shift offset is valid (less than the bit count). If you are sure that the offset is valid, use the "unchecked" version which should be faster.
