INTEGER OVERFLOWS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Depends on the data type. Typical binary sizes for integers include 8 bits, 
16 bits, 32 bits (the most common width for personal computers as of 2005), 
64 bits, and 128 bits

Ex.: 65536 % (65535 + 1) = 0

+---------------------------------------------+
 Limit:	65535 or 1111 1111 1111 1111
 Too big:	65536 or 1 0000 0000 0000 0000
 What's stored:	0 or 0000 0000 0000 0000
+---------------------------------------------+

or 2's Compliment

+---------------------------------------------+
 Positive limit:	32767 or 0111 1111 1111 1111
 Too big:	32768 or 1000 0000 0000 0000
 What's stored:	-32768
