This is how they do it already.
All coordinates in Protel are stored as 32 bit (binary) integers with the
LSB equal to one ten thousandth of a mil (0.0000001 inches).
Conversions and roundings are done to translate back and forth from
"internal" coordinates to coordinates that the user interacts with (mils or
mm).
