Noun

fixed point (plural fixed points)

1. (computing) A fractional-number representation with a fixed number of digits after the decimal point. Compare floating point and integer.
2. (mathematics) A value which is unchanged by a function or other mapping. Formally: a value x for which f(x) = x.^W

   The Bonan-Jeener's triple Klein bottle is not equivalent to the Boy's surface, as can be ascertained by the fact that a 120° rotation of the triple Klein bottle around its axis of symmetry yields no fixed point, whereas a similar rotation of the Boy's surface does yield a fixed point, which is its "umbilical point" as it were.
