A integer terminated by a point is read as an integer in base 10.
This syntax (Lisp and Maxima) is extremely helpful when working with
ibase set to e.g. hex base 16.

It follows that in your examples float sees different things.

(%i1) exp(10000.);
(%o1) %e^10000
(%i2) exp(10000.0);
(%o2) 8.806818225662922b4342
