Yes, that sounds like a good idea. Did you make any investigation on what is a suitable limit? > I do like the specialized function idea, as it can easily be done using > our current framework.

I guess a single header which is included is easiest to start with? Should the functions be implemented in C? or C and Fortran? Or C++ even? Are there any other functions except pow that needs special implementation? -- You received this message because you are subscribed to the Google Groups "sympy" group.
