This package provides functions to lookup bits in integers.

bitCoef : (Integer, NonNegativeInteger) -> Integer

bitCoef(n, m) returns the coefficient of 2^m in two complement representation of n.

bitTruth : (Integer, NonNegativeInteger) -> Boolean

bitTruth(n, m) returns true if coefficient of 2^m in two complement representation of n is 1.
