Comment (by anonymous):

 Here is one example:
 {{{
   barotropiceos_logrho(:) = log10(10.0d0**barotropiceos_logrho(:) *
 rho_gf)
 }}}

 This code first exponentiates a quantity, and then takes a logarithm. The
 code contains many other similar expressions. I believe this code was
 implemented as a literal translation from a publication, without
 optimizing its numerics.
