Be careful defining string representations of numbers.  It is a 
non-trivial

Int goes to the default type of float (which is currently binary FP) 
already
upon using the / operator.

This is not necessarily a good idea.  Exponentials are very useful in
financial situations and want to be decimals, not binary floats, in 
those
cases.
