-/** @file
-    Utility functions for performing basic math operations constrained within a
-    modulus.
-
-    These functions are intended to simplify small changes to a value which much
-    remain within a specified modulus.
-
-  NOTE: Changes must be less than or equal to the modulus specified by MaxVal.
