I suspect most programs that do acounting and other stuff for small
financial applications ended up being written in languages that did not
support decimal format.Note many database style languages may calculate
in decimal character data. Not too long ago floating point was 32 bit math
still done in software on 386's. 64/80 bit math was not a
option back then. Ben.
PS. Any idea when you web page will be back on line ,Hans?
