Getting "ValueError: invalid literal for int() with base 10" error when access section's margin

[YaroslavDrovolskyi]

Using python-docx 1.2.0, I get this error when access section.right_margin:

  File "docx\section.py", line 226, in right_margin
  File "docx\oxml\section.py", line 370, in right_margin
  File "docx\oxml\xmlchemy.py", line 193, in get_attr_value
  File "docx\oxml\simpletypes.py", line 27, in from_xml
  File "docx\oxml\simpletypes.py", line 402, in convert_from_xml
ValueError: invalid literal for int() with base 10: '0.218505859375'

Meanwhile, Word's document.xml contains following:

...
<w:sectPr>
    ...
    <w:pgMar w:bottom="0" w:top="1114.400634765625" w:left="0" w:right="0.218505859375" w:header="0" w:footer="720"/>
</w:sectPr>
...

This probles is similar to issues #1335 and #1475 which were resolved.
I would be grateful if you could suggest a solution to get around this. Thanks!
