Fixed point (mathematics) - Wikipedia

In computing, fixed-point is a method of representing fractional (non-integer) numbers by storing a fixed number of digits of their fractional part. Dollar amounts, for example, are often stored with exactly two fractional digits, representing the cents (1/100 of dollar). More generally, the term may refer to … See more A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor. For example, the value 1.23 can be stored in a variable as the integer value 1230 with implicit … See more Scaling and renormalization Typical processors do not have specific support for fixed-point arithmetic.

The purpose of this technique is to use integer arithmetic (int, long...) while being able to represent fractions.

Webthen 2 is a fixed point of f, because f(2) = 2.. Not all functions have fixed points: for example, f(x) = x + 1, has no fixed points, since x is never equal to x + 1 for any real number. In graphical terms, a fixed point x means the point (x, f(x)) is on the line y = x, or in other words the graph of f has a point in common with that line.. Fixed-point iteration
