Return the largest positive floating-point number MATLAB can handle.
Strictly this problem is about finding the largest floating-point number that MATLAB can handle _natively_, i.e. with _dedicated_, _built-in_ commands. Besides ad hoc workarounds, it is also possible to use Java objects to compute with arbitrarily large numbers. Cf. https://www.mathworks.com/matlabcentral/cody/problems/1833
