New submission from Peter VG <petervg at gmail.com>:
Since strings cannot reliably be converted to floats and back, plistlib should provide an option to treat the real datatype as strings/data or to use the Decimal library class. Currently, reading and then writing a real value can change its representation in the plist even if it has not been modified. For instance:
Read:
<real>0.015</real>
Written:
<real>0.014999999999999999</real>
or
Read:
<real>0.4</real>
Written:
<real>0.40000000000000002</real>
