+1 from me for those features which can be emulated for platforms which don't have the math lib function available and are not too esoteric (though many of those have already been added), e.g. cbt() may be useful. Now, with respect to the one mentioned in the subject, I'm not sure how useful this would be in the stdlib, since it's very much tied to whatever float type Python happens to use on a platform. Juraj: Could you provide some use cases, where such a function would help in Python applications ? (I can see use cases written in C, but due to the low level, find it hard to believe that people would use this at the Python level) Thanks, -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Experts (#1, Feb 06 2017) >>> Python Projects, Coaching and Consulting ... http://www.egenix.com/ >>> Python Database Interfaces ... http://products.egenix.com/ >>> Plone/Zope Database Interfaces ... http://zope.egenix.com/ ________________________________________________________________________ ::: We implement business ideas - efficiently in both time and costs ::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
