Screening the coding style of Large Fortran HPC Codes

Both interesting!

Concerning Namelists, how are treated real numbers concerning their precision? I am thinking about that recent post:

Can floating point literals be adapted by the compiler to double precision variable?

This is another common gotcha: Floating Point Numbers - Fortran Programming Language Gotchas — Fortran90 1.0 documentation and I wonder if the compiler could not simply take a code like this: integer, parameter :: dp = kind(0.d0) real :: x real(dp) :: y x = 5.35 y = 5.35 and it would internally treat it as: integer, parameter :: dp = kind(0.d0) real :: x real(dp) :: y x = 5.35 y = 5.35_dp In other words, it would look where the floating point number is assigned to and adapt it accordingly…
