[petsc-users] Number of decimals in Viewer

[Elias Goldmann]

Thank you both for the replies.
I write a few real eigenvalues to a file using PetscRealView. Do you really think going binary is better here? Why would that be the case?

Kind regards,
Elias

    You can simply edit the PetscRealView() src/sys/error/err.c function which is very simple and add more digits
