When I worked for a big insurance company (for more than 20 years),
we did all our insurance math using binary FP. After some problems
(rounding issues) in the beginning, it worked without problems, and
it still does today. It was driven by the design decision to have the same
software working on all platforms, Windows, OS/2, all sorts of Unixes,
and IBM mainframe, and to use C to do this. The project started in 1992
and was in hindsight very successful. Before that, the insurance math was
done using Mainframe ASSEMBLER.
I conceived and held the C classes to enable the existing ASSEMBLER and
PL/1
developers to code in C for all the different platforms in the first years.
Later I worked on the project as a developer and consultant.
Kind regards

Thanks for your support.
One of the programs does heavy use of FP variables (mortgage calculation).
I hate to ask, but *binary* FP for financial calculations?
