That works fine, but I found out that a "monetary" value above 20

million Euros ( > 2^31 cents ) is not stored as an integer, but as a

double. As I said, it seems to work and the double seems to stick to

its "integer" properties, but I want to monitor very closely what

happens with that "double" if I grow bigger and bigger values.

Never heared of bigints?http://search.cpan.org/search?query=bigint&mode=all

Yes, I heard of the bigint::* modules, they construct a replacement of

all mathematical operations, but that carries an overhead and it lacks

control:

==> time/memory overhead: bigint variables are objects.

==> lack of control: there is no logical limit to how big a bigint

can get.

I want to stay with the standard built-in "int / double" arithmetic,

but I want additional control of the transition between the (as I see

it) 3 types of numerical values:

type 1. (int)

type 2. (double, with only integral values)

type 3. (double, with free decimal values)

This control should be implemented efficiently, hence my preference

for subroutines written in C.
