============== Bitmask Module ============== The central part of this module is the ``bitmasks_module.f90`` file. It contains the constants that will be used to define on which kind of integer the bitmasks will be defined. In the program, when an integer ``X`` is used to represent a bit string (like a determinant for example), it should be defined as, for example: .. code-block:: fortran use bitmasks integer(bit_kind) :: X The ``bitmasks_routines.irp.f`` contains helper routines to manipulate bitmassk, like transforming a bit string to a list of integers for example. Assumptions =========== .. Do not edit this section. It was auto-generated from the .. NEEDED_MODULES_CHILDREN file by the `update_README.py` script. ``bit_kind_shift``, ``bit_kind_size`` and ``bit_kind`` are coherent: .. code_block:: fortran 2**bit_kind_shift = bit_kind_size bit_kind = bit_kind_size / 8 Needed Modules ============== ..
