Integers are whole numbers (numbers without a fractional part). For example, 134 and −125 are integers, whereas 134.23 and −0.235 are not. An integer can be thought of as a number in which the position of the decimal point is fixed: the decimal point is to the right of the least significant (rightmost) bit. For this reason, fixed-point representation is used to store an integer, as shown in Figure 3.4. In this representation the decimal point is assumed but not stored.
