Wrong results

If ALIAS-Maple returns a wrong result the most probable reason is that
the theoretical system of expression has not been correctly translated
into a C++ interval equivalent. This may occur if the expression
involves numerical values and the value of the `Maple` `Digits` variable has a low value (by default the value is 10).
With a too low value there may be a
round-off of any numerical values that may indeed cause a solving
problem. Hence `Digits` and the ``ALIAS/digits`` of
ALIAS-Maple should be set to a large value (typically 40).

You must also be careful with expression involving rational numbers
that may be not translated correctly in C++ (for example 3/9 is usually
quite different from 3./9.).
