I am not an expert in this, but I have seen lots of rants and arguments
on this over the years.

As I understand it the core problem is needing base 10 numbers not base
2 ones – converting between them causes problems – and using hardware
floating point does not have enough accuracy for compliance with
requirements of FCA for financial calculations.

There are various people on the ACCU general mailing list and the LJC
emailing list who know much more about this than I do as they work on
these things on a daily basis. I could ask there for pointers as to why
money types are such an obsession.
