I am quite interested in a fixed point data type. I had produced a working model some time ago. Maybe I can use some of these new efforts to provide good examples as a guide. ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org

Hi Tod, Would you consider bundling the quaternion dtype with your package. I think everybody wins: your package would become stronger and Martin's dtype would become easily available. Thanks Val On Sat, May 5, 2012 at 6:27 AM, Tom Aldcroft aldcr...@head.cfa.harvard.eduwrote: On Fri, May 4,

Would you be interested in carrying Martin's package forward? I'm not opposed to having quaternions in numpy/scipy but there needs to be someone to push it and deal with problems if they come up. Martin's package disappeared in large part because Martin disappeared. I'd also like to hear
