It can be very useful to have a base 10 exponent representation in
certain situations where you need to have the exact same results in two
systems (like a third party ERP server versus a client side
application). Base 2 exponents are tricky (incorrect) when you read ascii.
E.g. I have resorted to using Decimal in Python just to avoid the weird
round off issues when calculating prices where the price is given in
fractions of the order unit.
Perhaps a marginal problem, but could be important for some serious
application areas where you need to integrate D with existing systems
(for which you don't have the source code).
In fact, I've already prepared the code for that, but commented it out
for now, because I wanted to have an efficient algorithm for converting
double to Decimal and because we should probably first add a Decimal
type to Phobos instead of adding it to the JSON module.
