    0 references
    The paper addresses \(\mathcal M^2\)-computability of real numbers. It is shown that certain significant real numbers are \(\mathcal M^2\)-computable. It is also shown that the set of \(\mathcal M^2\)-computable real numbers is closed under the elementary functions of calculus.
