Last time I looked at it, it was not easy either, because there was too much inline asm for 32 bit float, so, was not just switching some typedef. qreal as float also causes a lot of other problems because everybody expects qreal to be double, even when expanding those inline functions with a constant argument, need to cast it to float or it will not compile. Most trouble I had was python bindings, because there are too many dynamically generated files, and it is not trivial to patch those to create temporary vectors to convert float vectors to/from double vectors. > - ajax Paulo -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
