For what it's worth, there are, in my opinion, better ways of hosting something like SymPy Live and SymPy Gamma than the App Engine. So if you are interested in a project like this, don't be afraid to look into and suggest alternatives. See for instance tmpnb.org. Aaron Meurer On Thu, Mar 10,

Re: [sympy] Re: How do you replace a function argument with a float?

That is the issue here. The problem is that undefined functions do evalf name lookups. For example In [9]: Function("sin")(1.0) Out[9]: 0.841470984807897 We should change it so that only direct subclasses of Function do this, not UndefinedFunctions. In the mean time, Jason, a workaround would

Also type(phi) gives sympy.core.function.UndefinedFunction. This is confusing. On 11 March 2016 at 00:31, Aaron Meurer wrote: > Since this seems to break only when the function name is "phi", this > looks like an instance of https://github.com/sympy/sympy/issues/6938. > But

Since this seems to break only when the function name is "phi", this looks like an instance of https://github.com/sympy/sympy/issues/6938. But I'm not quite sure what other SymPy function is named "phi". I didn't find any in a quick grep. Aaron Meurer On Thu, Mar 10, 2016 at 1:54 PM, Sartaj
