Page 1-39 - At a somewhat more fundamental level, of course, they are essentially binary machines ,but the hexadecimal notation allows a considerably more compact external notation. As was true for our hypothetical computer, each different mode or type of information to be saved in the memory has an appropriate word format for its internal representation. For FORTRAN programmers (see Section 2.24) the most important formats are those for the integer and floating point number representations. Words of integer...
