Thanks to all who replied to my previous questions. Those functions work
fine now. Here is another question - I apologize if it has been asked before.
I need a function
that returns True if expr, which is generally a flat list, contains
only integers or floating point numbers, and False otherwise.
Rational numbers such as 1/2 are considered symbolic for this test; so is
\[Pi] or Sqrt. Appearance of any symbol, as in 2.0*a+3.5, makes it False.
As in previous questions, this should work on versions >=4.0.
Use: unified printing of simulation data structures in table formats.
Expressions containing only integers or floats are filtered through
PaddedForm and ToString, others through Symbol. The end
result (a flat table of strings) is filtered through TableForm with
