I posted this because I am quite interested in how software designed for non-programmers deal with floating point numbers. I personally am intimately familiar with IEEE754 double-precision numbers due to their prevalence in programming languages. It is a little bit surprising to me to learn that previous versions of Apple Pages, Numbers, and Keynote used binary coded decimal and now use decimal floating point.
