Fixed point types

WebA fixed point (sometimes shortened to fixpoint, also known as an invariant point) is a value that does not change under a given transformation. Specifically, in mathematics, a fixed point of a function is an element that is mapped to itself by the function. WebMar 3, 2016 · frangio mentioned this issue.
