 integral types for now, these come in four major varieties:

 On the Intel architecture numbers are represented *little endian* meaning lower
 significant bytes are stored in lower memory addresses. The whole memory
 representation for a value is partitioned into *high bits* and *low bits*. For
 example the hexadecimal number ``0xc0ffee`` as a  DWORD is stored in memory as:
