Though Maple provides routines to express integers or floating in different
integer bases the output looks not as nice as I want to have it.
And for example it does not work as expected using the 'simple ways' (while
for hex there is no simple way for floats):
Digits:=16; # for all the following
x:=frac(evalf(Pi)):
x:= x* SFloat(1,-14);
...
