We've found COLECurrency very useful for precise fixed-point caclulations.
        However, more decimal places would be very useful; only four seems
        to be a waste since nobody I know has ever found a use for the
        hundred quintillions of whole numbers that COLECurrency will
        store...  we could easily give those up and limit ourselves to 999
        trillion whole numbers.

Anybody know if there are plans to expand this object type to more decimal
        places, or if there is a good way to expand it?  This could include
        a third party solution or library.

Cheers
Rob

You should upgrade to MFC 4.2B by installing the patch as soon as possible.
Without the patch, MFC (and, therefore, your programs) are only compatible
with beta versions of various operating system components, and without
the patch you'll  necessarily run into trouble sooner or later.

There are none.

The book "The Art of Computer Programming" contains outstanding algorithms
for various fixed-point and floating-point operations.  It's easy to implement
the algorithms in C or C++, and they're very efficient.  You could tailor them
exactly to your needs.

           This performance was not lip-synched.
