While decimal floating point may be better than binary floating point for some applications, such as currency calculations, it would be unsuitable for other applications such as graphics. Doing advanced client-side graphics in JavaScript is an increasingly popular application. For example, see Processing.JS, Algorithmic Ink, Mozilla's recent image filtering demo, and any of a number of charting and graphic applications. Using decimal floating point is unacceptable for these kinds of applications - the performance would not be acceptable. So we should not go down a path based on the assumption that binary floating point can be removed. I agree with you and Brendan that these issues are better resolved in Harmony.
