Abstract
We develop a unified, information theoretic interpretation of the number-phase complementarity that is applicable both to finite-dimensional (atomic) and infinite-dimensional (oscillator) systems. The relevant uncertainty principle is obtained as a lower bound on {\it entropy excess}, the difference between number entropy and phase knowledge, the latter defined as the relative entropy with respect to the uniform distribution.
