This application contains a terminal S during the limits of digital functions as well as the notion of continuity.
We first define the various possible limitations there for a function and the concept of asymptote to a curve.
Also shown are the various types of transactions on the limits and some properties for lifting some indeterminate forms.
Then addressed the limitations of composite functions and theorems of comparison and supervision limits (squeeze theorem).
We end this course by the notion of continuity with some examples and against-examples (common functions, function integer part) and the intermediate value theorem and its corollary in the case strictly monotone (bisection theorem).

This course is illustrated with examples and exercises corrected.
