This is pretty, but not what I really want and not what I think would be the real killer addition to Sage. What I want is a spreadsheet that can take the symbolic results of Sage and have some columns represent the numbers I want to substitute into the symbolic expression and another column represent the numeric result. In other words each row would be a compact way to running lots of calls like F(x=__, y = __, z = __, q = __).n(digits = __). What I'm imagining is a fancy interact, but it would be nice if it could look like a spreadsheet and the user could decide which column contained which variable and function. I haven't tried building one, but think starting with one of these javascript spreadsheets might be nice (there are others I've looked at that seem as good as the one presented here). It would be good use of the server to only calculate complicated functions and have the spreadsheet do simple math locally.
