ECMAScript Version 5 Approved
systembug writes "After 10 years of waiting and some infighting, ECMAScript version 5 is finally out, approved by 19 of the 21 members of the ECMA Technical Committee 39. JSON is in; Intel and IBM dissented. IBM is obviously in disagreement with the decision against IEEE 754r, a floating point format for correct, but slow representation of decimal numbers, despite pleas by Yahoo's Douglas Crockford." (About 754r, Crockford says "It was rejected by ES4 and by ES3.1 — it was one of the few things that we could agree on. We all agreed that the IBM proposal should not go in.")
Until we get a slick gui editor for javascript+svg animation, no.
In other words, we need GNU Ecmas.
Even easier would be to base all the system on cents. After that it's extremely easy to convert that cents value into a dollar/cents string.
