Changing all doubles everywhere with long ones is not needed. 64-bit
double provides about 16 decimal places that is more than sufficient in
most cases. The only place where this might be crucial is linear algebra
routines (for example, on computing scalar products). However, it would
be better to use something like BLAS for this purpose.
