There are two tables in the paper. Table 1 is for EiC, the freely available
C interpreter used in the paper as a learning tool. Int is a 32 bit object
in EiC, with the associated signed and unsigned range. Table 2 is for
the C18 compiler used for the robot controller, where int is a 16 bit
type, with the associated signed and unsigned range. The text discusses
the issue. I hope that Table 2 is consistent with the data in IFI documents,
and the MPLAB C18 compiler documentation, it has been checked in
the past.

If you note a difference, please identify the document and page number.
