An IEEE 754 format is a "set of representations of numerical values and symbols". A format may also include how the set is encoded. A floating-point format is specified by • a base (also called radix) b, which is either 2 (binary) or 10 (decimal) in IEEE 754;

WebIn a fixed point number we fix the scale factor in advance. So for example to represent numbers in the range 0 to 1 inclusive we might use a 32-bit unsigned number with a scale factor of 1/(2 32-1). In a floating point number we allow a range of scale factors to be chosen.
