Atoms are *not* stored as 32-bit long integers.
Someone else said the same thing recently,
so I'd better clarify. Atoms are stored (when necessary) as 64-bit
floating-point values. If you are only interested in storing
integer values in an atom, you can have integers up to
about 15 decimal digits (52-bits) without losing any precision.
