It is a bit naive for computer scientists to club integers and reals
as mathematicians do given that for real numbers, even equality is
undecidable!
Mostly when a system like mathematica talks of real numbers it means
computable real numbers which is a subset of mathematical real numbers
(and of course a superset of floats)
