What is the best book on numerical methods?
I need to use some heavy-duty numerical methods - quadrature, interpolation, ODE solution with expensive derivative terms, etc. What's the best book on the subject?

I will be using packages where I can, but I can already tell there will be times when I need to write my own routines...
