That's what I'm saying (but you would get float64 out --- but if you didn't want that then you would have to be specific).

I did abstract the notion to a C-API: PyArray_ConvertToCommonType and implemented the scalars-don't-cause-upcasting part of the ufunc rules in that code. But, I followed the old-style Numeric coercion rules for the rest of it (because I was adapting Numeric). Right now, unless there are strong objections, I'm leaning to changing that so that the same coercion rules are used whenever a common type is needed. It would not be that difficult of a change. -Travis ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
