I don't think it says that. First of all, the first paragraph is a "should" wherease the second paragraph contains no qualification. So I would think the second quoted paragraph trumps the first. Moreover, "treated as if specified with a mantissa width of 53" is not the same as "1.0 is synonymous 1.0|53", at least by my understanding. I'm reluctant to make more than minimal changes to the wording, and thus relucant to delete the first paragraph. Can you suggest something that makes it clearer that doesn't risk changing the substance? -- Cheers =8-} Mike Friede, Völkerverständigung und überhaupt blabla _______________________________________________ r6rs-discuss mailing list [email protected] http://lists.r6rs.org/cgi-bin/mailman/listinfo/r6rs-discuss
