Good morning everyone! I like the posts from Brendan which occurred while I was sleeping.

We agree that rushed and user-hostile is in no-one's interest. While others may disagree on some specifics, I sense that Brendan and I agree more than disagree on what is, and what is not, user hostile. I am going to continue to do my level best to get an un-rushed, user-friendly Decimal support into 3.1. If I succeed, great. If I fail, then hopefully there is some specific issues that we can all agree upon which needs to be worked. > I am interested to see what Sam can pull off, in code more than spec. > I don't doubt the spec can be done, given design decisions from IEEE > P754 and some freedom to match JS design impedance.

Rob's comments, while valuable, aren't as much a concern to me than the fact that no-one has yet to review my code. A modest request: if the code could be reviewed and feedback provided to me with sufficient time for me to address the comments and the code to be integrated into a nightly build, by default disabled, in time for the Redmond meeting, I would appreciate it. I see you (Brendan) asked a question about Object.eq. Instead of trying to lead you to the conclusion that those of us on the bi-weekly "3.1" calls have provisionally made, let me try to get your input on the topic. Let's posit for the moment that adding two nickles and calling toString() on the result produces "1.10", with the trailing zero. I realize that some may disagree, but for the moment, assume that to be true. Furthermore assume that 1.10m > 1.09m and that 1.10m < 1.11m. Given the above, as well as your knowledge of ES history, what would you expect the results of evaluating the following two expressions to be: 1.10m == 1.1m 1.10m === 1.1m Depending on your answers, there may be a followup question. > /be - Sam Ruby _______________________________________________ Es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
