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.
