Documentation complex logarithm https://gcc.gnu.org/onlinedocs/gfortran/LOG.html

[C.Friedrich]

The LOG function returns the principal value of the complex logarithm
whose imaginary part omega must be in the range -pi < omega <= pi.

GFORTRAN does it correctly but the online documentation
https://gcc.gnu.org/onlinedocs/gfortran/LOG.html gives -pi <= omega <=
pi. Perhaps this should be corrected.
