"""Functions for reporting filesizes. Borrowed from https://github.com/PyFilesystem/pyfilesystem2

The functions declared in this module should cover the different
usecases needed to generate a string representation of a file size
using several different units. Since there are many standards regarding
file size units, three different functions have been implemented.

This is typically the format used to advertise the storage

    actually a storage capacity of more than *256 000 000 B*),
    or used by **Mac OS X** since v10.6 to report file sizes.

Arguments:
        int (size): A file size.
        int (precision): The number of decimal places to include (default = 1).
        str (separator): The string to separate the value from the units (default = " ").

Returns:
        `str`: A string containing a abbreviated file size and units.

Example:
        >>> filesize.decimal(30000)
