In mathematics, a fixed point (sometimes shortened to fixpoint, also known as an invariant point) of a function is a point that is mapped to itself by the function
1 Positional notation in which corresponding places in different quantities are occupied by coefficients of the same power of the base Contrast to floating point
or defining point - a reproducible standard value, usually derived from a physical property of a pure substance For example the triple point of pure water defines a temperature of 0 010°C
Number system in which the binary point is fixed or in one place for all representations
Of a function, f: X-->X, f(x)=x Of a point-to-set map, F: X-->2^X, x is in F(x) The study of fixed points has been at the foundation of algorithms Moreover, particular fixed point theorems have direct application in mathematical programming
A special trajectory of the dynamical system which does not change in time It is also called an equilibrium, steady-state, or singular point of the system
A point in the upper dorsal spine which is considered as aligned to the vertical axis and about which longitudinal rotation of the cervical spine and the head take place as a unit when abnormally moving into either the right or left frontal plane
A method of representing numbers in a computer in which the decimal (actually binary) point is considered to occur at a fixed position within the number
A projectile point permanently attached to its shaft, as opposed to a toggling head
A reproducible temperature at the equilibrium point between the phase changes in a material For example, the triple point of water at standard atmospheric pressure is 32 02ºF (0 01ºC)
