Since you seem to know the internals quite well: do you know of some kind of reference or summary regarding the accuracy of the internal 15-digit functions? I recently learned that the natural log may be more than 1 ULP off, so I wonder how accurate (or not) the other functions may be. I would also be interested very much in information on this matter regarding 10-digit devices with 13-digit internal precision, for instance the 41-series. Dieter |
