WebIn mathematics and computer science in general, a fixed point of a function is a value that is mapped to itself by the function. In combinatory logic for computer science, a fixed-point combinator (or fixpoint combinator) [1] : page 26 is a higher-order function that returns some fixed point of its argument function, if one exists. Formally, if ...

A fixed point number just means that there are a fixed number of digits after the decimal point. A floating point number allows for a varying number of digits after the decimal point. For example, if you have a way of storing numbers that requires exactly four digits after the decimal point, then it is fixed point.
