Dani, We all know the variants of round and their behaviour differences. I'd be mooost interested if you gave a little try to interoperate... Take round(-3.5) and evaluate it in Maple, Mathematica, Wiris, Yacas, Sage, Maxima, ... (ideally you should also try Excel, Apple Numbers, OpenOffice, ... but I doubt they understand MathML-Content or OpenMath). paul Le 5 nov. 2012 à 13:16, David Carlisle a écrit : > On 05/11/2012 11:48, Daniel Marques wrote: >> Hello, >> >> We need to represent expressions involving the "round" function in >> content MathML. >> >> For ceiling and floor there exists the tags <ceiling/> and <floor/>.
