Fixed point The fixed point of a function, f is any value, x for which f x = x. A function may have any number of fixed points from none (e.g. f x = x+1) to infinitely many (e.g. f x = x). The fixed point combinator, written as either "fix" or "Y" will return the fixed point of a function. See also least fixed point. (1995-04-13). Source: The Free On-line Dictionary of Computing.

Specialty Definition: Fixed point

(From Wikipedia, the free Encyclopedia)

In mathematics, a fixed point of a function is a point that is mapped to itself by the function. For example, if f is defined on the real numbers by f(x) = x2 − 3x + 4, then 2 is a fixed point of f, because f(2) = 2.

In computing, a fixed-point number representation is a real data type for a number that has a fixed number of digits after the decimal (or binary or hexadecimal) point. For example, a fixed-point number with 4 digits after the decimal point could be used to store numbers such as 1.3467, 281243.3234 and 0.1000, but would round 1.0301789 to 1.0302 and 0.0000654 to 0.0001. These fixed-point presentations are usually used, if either the executing processor does not have any floating point unit (FPU) or performance outrules exactness.
