Fixed-point arithmetic: History & Applications

In computing, fixed-point is a method of representing fractional (non-integer) numbers using an integer together with an implicit or explicit fixed scaling factor. Dollar amounts, for example, may be represented with exactly two fractional decimal digits, corresponding to cents (1/100 of a dollar). More generally, fixed-point values can represent integer…
